At eight a.m. the board fills fast,
With acids strong and bases past.
Some dissociate all the way,
Some pause where Ka says they may.
Add stress and watch equilibrium shift,
Le Châtelier gives systems a lift.
Buffers stand, the pH stays true,
Holding balance like they’re trained to do.
In every reaction, push and pull,
Nothing stays one-sided or dull.
Even half awake, I finally see
Chemistry loves equilibrium.
~ Piper
A weak acid and its conjugate base,
A pair who cannot be replaced.
In solution together
There isn’t a buffer who’s better
But here comes along OH!
OH and weak acid just happen to meet
A reaction could not be so complete.
But weak acid is so plentiful
And conjugate base so wonderful
Just how could weak acid leave?
Conjugate base, alike in molarity
Ensures a lack of disparity.
Together they resist,
A pH change almost amidst
The pH and pKa in close similarity
~ Gavin
When I was learning buffers
Oh how I suffered
But there’s no time to lament
Problems as hard as cement
Because I know Chem1C will make things tougher
~ Jason
We fill the burette with HCl,
When we know the weak base will rebel.
Not even adding the acid slow,
And yet the pH never gets low.
It’s like it’s under a spell.
~ Marigold
A Buffer keeps the pH in line
Acids and bases are divine
When the two are the same
pKa is the game
And balance is just fine
~ Teddy
Better Together
A weak acid, its conjugate base,
Or, likewise, the reverse
They function all the same.
Together they keep pH in its place,
Or rather I should say, [H+] and [OH-].
Perfectly balanced, there's nothing much stronger,
Than a buffer so equal in volume,
So equimolar.
pH is pKa, that's the way to tell,
What solution you want,
To keep everything going well.
From shampoos and medicine,
To even your own blood.
Life as we know it would not exist,
If not for a buffer, doing its job.
So, If you’re looking for something to save the day,
To hold the pH, to keep things the same.
Don’t fret long.
Don’t run away.
A buffer, A buffer,
A buffer is on its way.
~ Claire
Shout out Bronstead and Lowrey, with out you this never woulda been possible
Your strong acids dissociate so fast they're Unstoppable!
But what happens when they're introduced to a strong base through titration?
The base gets added a drop by drop like menstruation
Then once the equivalence point is reached we pause
The pH is guaranteed to be seven, those are the laws
But not all reactions behave so similarly
Weak acids differ particularly
Take hydrofluoric acid for example
You’d expect the pH to change when the hydrogen added is ample
But this doesn't have to be the case
We can add fluorine, the conjugate base
And so a buffer solution is produced
The H+ created more weak acid, I’ve deduced
So our pH stayed level all thanks to Flourine
Now its time to eat a Professor Feldwinn Tangerine
~ Gavin
Behold chapter seven
A tale to tell
Notes to spin
Into a poem (hopefully) well
Acids give protons to the solution
Bases on contrary take
The terms weak and strong do not warn
Of danger, but tell how much it dissociates
Weak acids and bases partially dissociate
For which Ka and Kb denote extent
Strong acids and bases completely dissociate
With none of their original selves present
pH gives information on proton concentration
For quantifying the acidity of various solutions
Through equation -log(H+;concentration)
One arrives at a mathematical conclusion
Much I could elaborate
And dig into the material deep
But lacking time I find my fate
Is to lay down this work and sleep
~ Ellie
Deep within the molecules of life
Acids and bases in constant strife
A give and take of sought after protons
Acid and bases are chemical icons
To measure their acidity we use pH
Just take the -log with a 10 for the base
A sevens in the middle that is known as neutral
Trying to take a proton from one of these is futile
When the pH is lower than seven it’ll cause a sour taste
Dunk the litmus paper you’ll see the blue erase
Acids turn the paper red while bases keep it blue
All this stuff is measurable based on the papers hugh
When the acids are strong that go through full dissociation
However if they’re weak they’ll be less summation
~ Alex
An acid gives its H+ away,
A base reaches out to stay,
Two become one in shifting roles,
Conjugate partners, trading souls,
Following the Bronsted-Lowry way.
Some break apart, strong and clear,
Some hold back, balance near,
pH tells where waters lean,
Seven’s calm, a quiet scene,
H+ and OH- appear.
~ Aria
It’s 8 a.m., the lights beam loud,
slides shine bright above the crowd.
Dr. Feldwinn speaks with no delay,
Chemistry never waits, wake up, okay?
A Bronsted–Lowry acid gives,
a proton is lost, and a base then lives.
H+ moves fast from bond to bond,
breaking ties, forming one's beyond.
HA dissolves, and its proton is freed,
A- remains, it’s conjugate indeed.
pH drops low when H+ is high,
H+ is fundamental, it’s the reason why.
~ Audrey
In water a strong acid dissociates completely
A weak acid won't dissociate quite as neatly
The concept of strong and weak bases are the same
Weak acids and bases have K values to claim
In the test sheet the values you will find discreetly
~ Andrew
Acids form positive H+, it is kind, it donates
Bases form negative OH-, its greedy, it takes
Strong acids & bases like HCl and NaOH fully dissociate
The stronger it is the weaker it conjugates
Hydrogen and hydroxide always relate
An acidic pH of 2, lemons are great
to the left of the scale it resonates
A basic pH of 12, ammonia will make you feel faint
to the right of the scale its waits
A neutral pH of 7, water is calm and it hydrates
In the middle it mediates
Split a salty compound to identify its traits
When the product is strong a neutral ion it formulates
DI water is neutral it states
rain of an unpolluted area, a basic pH it creates
In industrial areas acid rain it generates
~ Summer
An acid donates a proton, H+ in solution,
Forming its conjugate base by dissociation.
A base accepts protons, reversing the role,
Linked pairs defined by equilibrium control.
pH quantifies hydrogen ion activity,
pOH tracks hydroxide concentration objectively.
Their logarithmic sum, fourteen at standard state,
Defines aqueous systems at equilibrium fate.
Strong acids ionize with complete extent,
While weak acids establish equilibrium, partially spent.
Concentration governs magnitude, not just identity,
In the quantitative language of acid–base chemistry.
~ Elizabeth
Dissociation constant is their weapon
For a pH high or low, starting at seven
A proton to accept or throw
Only they’d know
Acids and bases is the lesson!
~ Kaylee
Acids,
Aren’t so placid
They relish in conjugation
With bases, focused on reorganization
Acids and bases
Focused on homeostasis
Their active protons
Ready to move and hop on
Acids and bases reach elysium
Finally, being in a state of equilibrium
~ Gabi
Acids and Bases
When you're trying to feel more positive, and all you need is that H+.
An acid will always be so kind, and donate it without a fuss.
Bases are the opposite, to acids they are quite strange.
A base will accept your H+, and its sign value will have a +1 change.
Acids have a low ph number, but trust me, they are not flaccid
In Breaking Bad we see the true power of Hydrofluoric acid.
Bases again differ, they don’t burn things at the touch.
They’re ph is higher, and slippery and soapy, they are too much.
They seem quite different, but truly they are siblings not so different from each other.
Using conversions and icetables with one value, you can find that of its brother.
They’re ph and poh will always add to fourteen.
1.0e-14 is where the Ka and Kb product convenes.
In truth, acids and bases compliment each other quite well.
In titrations and acid base reactions, they work together so swell. In Equilibrium reactions, they both play their role.
Just make sure you don’t scoop any of them up, and eat them from your bowl.
~ August
An acid kindly donates a proton to an accepting base in need
In an equation with all weaks, the reaction will proceed
But with a strong acid and strong base staring in your face,
All that’s left is simply H+ and OH-
A pH below 7 is in the acidic range
While above that would be basic, though the equation stays the same
pH equals negative log of H+ concentration
Now we know what’s for cleaning and what's for food disintegration
~ Ava
Low pH means acidic
Now we're getting scientific
If we add more H plus
That causes lower pH for us
Warning strong acids on your skin can be horrific
~ Nina
It amazes me how Ka, just a number so small,
Can tell how many ions choose to leave it all.
They step into water like people into a crowd,
Some shy and some bold, never speaking aloud.
With simple math, we count their choices, reveal all their fates
~ Junbo
“Between H+ and OH”
On a scale from zero to fourteen wide,
Lies a place where acid and bases reside,
The scale chemists trust to clearly tell,
The pH scale is where these strengths dwell.
When H+ ions overpower the base,
The number falls and its an acidic place
Sour solutions fierce and strong,
Where hydrogen ions gather along.
But when OH begins to grow,
The pH rises and the solution starts to flow
Seven stands neutral, all is fair,
Pretty much pure water balanced with care.
With H+ and OH- side by side, neither is able to win the tide.
~ Regan
Acids donate protons with ease,
Bases accept them readily.
Defined by Bronsted-Lowry’s view,
Conjugate pairs form something new.
Strong acids spilt without delay,
Weak ones only partly give way.
Ka and Kb reveal their strength,
Measured by reaction length.
As H+ rises, pH falls,
pOH climbs when OH- calls.
Salts dissolve and shift the scale,
Acidic or basic, trends prevail.
From gases released into the air,
Acid rain forms, chemistry’s there.
~ Ashton
When acids and bases reach equilibrium,
The forward and reverse flow find their rhythm.
Le Châtelier will show
Which way the system will go,
Predicting the shift with minimal delirium.
Strong acids ionize with no hesitation,
Weak ones show only partial dissociation.
The Ka will tell
If they ionize well,
And guide you to the right calculation.
A base can grab a proton with pride,
Forming its conjugate on the side.
pH above seven?
It’s basic, not heaven.
Check concentration, don’t let it slide.
If Kb is tiny, the base is mild,
Strong ones react like a wild child.
Percent ionization low?
Use the x to show
Approximation keeps the math reconciled.
Remember to log when you’re finding the pH,
Mistakes are common, but they’re not your last test.
Double-check your math,
Follow each path,
Soon equilibrium problems will feel like a fresh breath.
~ Ashley
Tanka style poem (5-7-5-7-7)
Products, reactants
Shifts to the right and shifts, left
Le chateliers (le-cha-te-li-ers)
Adding and subtracting heat
the system fights disturbance
~ Aika
The forward reaction runs fast
The reverse matches it refusing to come in last
In dynamic equilibrium
No reaction takes the fun
As they combine to produce a blast
~ Oliver
Equilibrium, equilibrium,
Seems static in the system,
Yet proceeds forward and backward,
Simultaneously, combating against changes.
Products over reactants’ base,
With coefficients raised.
That’s K, the equilibrium constant,
Never change with concentration or pressure.
When the coefficient multiplies,
The change to K applies:
The factor is the exponent.
That’s the new constant.
When the left and right swap,
The constant will flip;
When two reactions add,
Constant will be multiplied.
Want some ice in soda drinks?
Equilibrium says yes!
ICE table is important in calculation,
It tells how the equilibrium changes.
Initial starts the first,
Followed by the change in nx,
Involving the coefficients, equating with constant,
We can find many ways to success.
‘Guess and check’ is useful,
But try simplify first.
Once get the result,
Bring it back to recheck.
Concentration is found,
Everything is done.
Whenever the things change,
We can solve it out.
~ Ziang
Dear Equilibrium,
You have this desire to be seen as dynamic
Others will claim that you already have it
You’ll find the truth in something pragmatic
Reactions will meet, it’s all just a havoc
Pushing and more pushing has led to a habit
Reverse and forward they move how nomadic
Little do you know they can ease all your panic
They continue to argue, but it’s nothing illicit
The solution that awaits will end all this manic
Their problem is solved with one key mechanic
Two sides, one fate, both refuse to just quit
Come together over time, their movement now civic
Don’t you see that their rates are simply organic
Those rates must be equal, two sides, one spirit
Balance has been made it almost feels mythic
Your two sides have done what others see cosmic
Now you understand that you’ve always had it
Equilibrium you are nothing short of dynamic
SoundCloud
~ Sydney
Get the day started with Feldwinn's lecture
A fervent tale of equilibrium
a reversible reaction structure
where forward and backward are in rhythm
the rates are the same, and concentration
stays constant with gas and aqueous state
though particles shift in silent motion
the balance remains, unchanging fate
exponents come from the coefficients
products are favored the larger K is
equilibrium ain't equivalence
temp shifts right and left so beware on quiz
Le Chatelier states when stress is applied,
The system acts to offset the tide.
~ Jenna
It can run forward and backward
like a pendulum that swings.
remember it is dynamic.
like a hummingbird's wings
Q is its quotient and K is its constant
you need it to understand the theory of Bronsted
while it is best to make an assumption, if you take it one step at a time
The fundamentals of equilibrium will make Chem 1B a piece of pie.
~ Maisy
There once was an ICE table so neat,
With I, C, and E in a rowed little sheet.
You start with what’s there,
Then change with some x flair,
And end praying algebra admits defeat.
~ Julie
Solve for equilibrium and find k or q
You may have to raise the concentration to the power of one or two
The rate of the forward is equal to the rate of the reverse
This is what equilibrium is for all chemistry in the universe
~ Maya
Equilibrium, forward, reverse
No reaction I can see, so perverse!
Reactions still go
Even though, you know!
They shift back and forth, just to say hello
~ Caylei
