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

@brettconner3450 2 месяца назад

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

@amyhughes2149 2 года назад

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!

@noahrecknagel7142 Год назад

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 Год назад

You're welcome! Good luck thsi semester!

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

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

@tomasb7645 Год назад

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

@gaby4061 8 месяцев назад

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 RU-vid 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!

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!

@rohitmenon9738 Месяц назад

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?

@tejsingh2309 8 месяцев назад

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

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

Hey vsauce Michael here

@indrajitbandyopadhyay9161 2 года назад

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

@sryblt Год назад

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

@michellesen1739 Год назад

u teach better than the professors at ucla

@jaybuckets3189 Год назад

Is a BAA table the same as ICF table?

@SiebertScience Год назад

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.

@jessicaadongo2838 3 месяца назад

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 4 месяца назад

What if you have a weak base and strong acid?

@adsfjkl4390 4 месяца назад

*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.
