Weak Acid / Strong Base Titration - All pH Calculations

[@amyhughes2149]

I've done these calculations so many times, but I always struggle to remember them. This step-by-step explanation was so helpful and the summary at the end will definitely help me to remember. It's hard having to teach myself the university coursework, but channels like yours are a live-saver, you're awesome for providing educational content like this!

[@johnyeap7133]

I think everyone watching this video just found the best explanation for pH at equivalence point on the internet at 8:50

[@brettconner3450]

bro I never understood it, andf this was so helpful, cuz my teacher also taught it wrong

[@irynlincoln4189]

You just explained a 2 hour lecture and 3 hours of practice with no progress into an 18 minute video!!!!

[@noahrecknagel7142]

man words can't describe the amount of gratitude I have for you right now sir, my chem teacher is awesome but obviously she can't help me every time when I do homework at home. your video really helped a lot, and even though you haven't made one on weak acid strong base reactions i could use this video to understand those as well. thank you again!

[@SiebertScience]

You're welcome! Good luck thsi semester!

[@tiddieman69420]

You're the actual GOAT. Just letting you know you saved a poor innocent soul struggling with gen chem 2 (aka me).

[@paes_3107]

same omg 😭 idk what my prof was rambling about

[@gaby4061]

This video wins the Nobel Prize for me! I was struggling so much with acids/bases in my gen chem college class and after watching this video I've done every single question correctly without fail. The way you broke it down into parts based on if the reaction has not yet reached/is at/is past the equilibrium point was the aha moment for me. Now I just identify what point the reaction is at and go through the corresponding steps like it's a piece of cake. Thank you so so so so so much!! I usually don't comment on KZbin videos but I felt the need to comment on this one because I have an exam today and I feel so prepared because of this video. Stuff like this really inspires me to become a teacher!

[@kavyak2243]

Thank you so much! This greatly helped me prepare for my chemistry final.

[@okeogheneigbru8875]

Your explanation is so simplified, thank you!!

[@jasonzhang7725]

Thank you for explaining it very efficiently and increasing my chemistry knowledge by 0.38%

[@Uncultivated_]

I love my Chemistry teacher to bits, but this was infuriating to learn, I just didn't get what was going on. This video was a lifesaver, I understand it a lot better!

[@decryptroblox]

I really enjoyed watching the video, the way of explanation is straight to the point and understandable with no unnecessary jargon. Keep up the great work!

[@tomasb7645]

BRAVO!!! Soo well done! Your flow and concise way of explaining the interconnectedness of ...everything is AWESOME! Keep the videos coming!

[@glowstickspinalfluid]

i literally owe you my life for this

[@hanajurdi6567]

You're a life saver I was absent during this lessons explanation due to my sickness and my exams are soon this video is amazing thank youuuuu

[@andujarvis3961]

I haven't finished the video, but I'm already satisfied. Thank you so much Sir 🙏

[@AllTheButtons87]

Thank you so much for introducing me to the BAA table concept! That will help

[@ostrich8]

I love you Siebert. Thank you so much for this video!

[@musarratsalim81]

I love this. So informative, yet concise. Thanks for the video, really.

[@dariabalashova2665]

Really great video and explanations! Thank you

[@trystannorris5427]

saving me with these videos, thank you so much! you explain it in a very detailed and step by step method and work through the problems thoroughly, which is extremely helpful.

[@joyharfouche7482]

i think you just saveed my life

[@jplpz2323]

Sir, you are a baller and a gangster for this amazing explanation! You earned a subscriber!

[@Trynnagetmydegree__]

Thanks man it clarified the holes in my understanding, just gotta practice these! :)

[@Ace059]

Thank you. I finally found someone who showed how to calculate the OH - I was so confused.

[@Virat8059]

Thank you sir for the great explanation!

[@mayflowerimpact]

Why is Na ignored in the formula?

[@Rishkapish]

Day of AP chem exam bro. This topic is the only thing I don't got a grasp on and now I think I got it

[@SiebertScience]

Good luck on the AP exam!

[@shnoalimhamadkaram1594]

Thanks alot , you are clear it , by nice way .

[@pianolex5421]

Dude thank you so much for this video. So helpful you have no idea

[@dilmiupeksha6027]

Thank you very much sir.🙏🙏🙏🙏❤❤❤

[@anjanahere]

Loved the explanation. Thank u❤

[@vegetaiv9275]

Thank you so so so much! You are legendary! Why didn't my professor explain the weak acid / strong base titration like you marvellously did?

[@t4gguk]

this has no business being this hard im losing my mind

[@t4gguk]

this was so helpful tho

[@josiehanewich2296]

This is amazing thank you!

[@angiew6553]

Thank you for the amazing videos!! Super helpful for my homeschool experience :)

[@asuramunikavishadesilva371]

Thank you!❤

[@kishanthansiththiravel852]

blast it man... 🙌🔥 Thank you sooo much💥❣

[@Daniel-gk1dp]

You absolute legend!

[@Emmanuel2002]

this awesome atleast I'm getting ready for the exam

[@mehak8452]

Thankyouuu so much for this.. really helped me a lot!!❤

[@SiebertScience]

You're welcome 😊

[@BOLYANA]

ياشيييخ انت اسطورة والله

[@lilspacebunnny]

10:46 I don’t unterstand how u calculate the 50ml. It’s a really good video thank u!

[@michellesen1739]

tysm i was stressing so much

[@tejsingh2309]

Would all of this apply if we were doing strong acid weak base too? Is it just strong base strong acid that’s different?

[@prettyfaerie7]

great video!

[@nabilah7177]

Thank you!

[@austin7843]

You are a HERO!

[@SiebertScience]

Haha, thanks!

[@kyubeenkim9360]

Thank you sooooo much!!!

[@Jennagrays]

Actual GOAT❤ 🐐

[@baonrazi6375]

why the ice table, sometime u use in moles, sometime in concentration?

[@silentninja32]

You are a godsend, thank you!!!

[@SiebertScience]

You're welcome!

[@tatestamper5442]

Hey vsauce Michael here

[@cog592]

Why do you use the same Ka value in a different equation?

[@uzef8918]

made it seem sooo easy. thanks 10 fold :)

[@michellesen1739]

u teach better than the professors at ucla

[@rohitmenon9738]

How come at at 15:24 you don’t redo the ice table after the equivalence point. Wouldn’t the system want to create HCHO2 to maintain equilibrium, thus increasing the OH- concentration? I believe this would be a very small value but should it still be done?

[@inexp1]

amazing video

[@Danya-rkive]

ok to work on normality concentration then we convert it to moles ?

[@madelinemoscoe6168]

how do I know if the formate would gain or lose a hydrogen

[@DylanDossey-gl5lv]

God bless you

[@overclocked5422]

yeah, this isnt happening

[@jessicaadongo2838]

Please please if someone can,please reply me as soon as possible 😭 I have an exam tomorrow 😭...my question is,if the titration involves weak base against strong acid,how will you go about the calculations

[@anushashringi5458]

What if you have a weak base and strong acid?

[@adsfjkl4390]

*Disclaimer: I'm not 100% sure so you should probably fact check all of this* From my understanding you create a RICE table using A + H2O AH+ + OH- (A=base). Then solve for x. This can be used for initial and at equilibrium (keep in mind this is the concentration of OH- so you will need to find pOH then subtract from 14 to find pH. If you're not at equilibrium, convert your pKb to pKa then use the henderson-hasselbalch equation pH= pKb + log [A] / [AH+] If you are working with a base that accepts more than one proton, to find the pH at equilibrium, find the concentration of your conjugate acid then find the Ka for which ever Kb you are using. Next create a RICE table (in this example I'm using 2 H+ ions) AH2 2+ + H2O AH+ + H3O+ then solve for x and use the concentration of your hydronium ion to find the pH. The henderson-hasseblach equation should still work for more than one proton, just remember to you will be using different ammounts of hydrogen (still using 2 H+ ions like in the example above) the equation would become pH= pKb + log [AH+] \ [AH2 2+]. I hope this helps.

[@LorenzoVentura-f1l]

you saveddd meeeee

[@indrajitbandyopadhyay9161]

Can we not use Henderson-Hasselbach equation at or after equivalence point? salt hydrolysis is negligible before equivalence point?

[@sryblt]

I also confuse with this. Does CHO2- not affect the pH? Do you find the answer for it?

[@trueKENTUCKY]

slaps even at 500 level

[@jaybuckets3189]

Is a BAA table the same as ICF table?

[@SiebertScience]

Nope, they’re different! ICF tables are used in many equilibrium calculations. BAA tables are specifically a stoichiometry calculation to see what gets used up and what’s left over in a one-way reaction.

[@MayaTadmor]

oh my god thank yoy

[@SiebertScience]

You're welcome!
