Thanks for the video! I've been trying to understand how Buffers work with a simple explanation and you did it! Great job!

[@autumnrose3943]

Great explanation. So helpful. Thank you.

Thank you so much for this video. Such a simple concept, yet my lecturer overcomplicated it to "exhaustion". Much appreciated

[@TonyNguyen-it7vd]

[@emanekram3884]

I didn"t understand the point that when we add a strong base "OH" to the medium , It will combine with the HA to give A- which is strong conjugate base , so it will change the pH !
The conjugate base is strong because it comes from weak acid.

[@solshinez]

this made the explanation soooo easier. thank you so much

[@jyothiswaroop2964]

Nice simple explanation!!! Thanks a lot!!

[@junaid6730]

Thank you. By the way, it would be better to state that a buffer solution is made up of a weak acid(CH3COOH) and its salt(CH3COONa) or a weak base(NH4OH) and its salt(NH4CL)

[@pokemonjynx1019]

question - if the conjugate base of the weak acid is a strong base, then when u add OH, doesn't this populate the solution with strong bases now? so that would shift the pH towards the base

[@junaid6730]

Yeah, when OH^- is added, the weak acid combines with it and gives out water and strong base and if you don't add H^+ to the solution, then the strong base will be there and would populate the base concentration in the solution. But the experiment shows that pH has not changed, so there is something wrong with our reasoning.

[@junaid6730]

I got it! In my textbook, it says that a typical buffer solution is made up of a weak acid and its sodium salt. So let's take ethanoic acid as our weak acid. Then, a buffer solution would be made up of ethanoic acid and sodium ethanoate salt. Then, if we add OH into the solution, ethanoic acid which is the weak acid would deal with it and give out water and a strong base which is CH3COO^-. Since, sodium ethanoate is a salt, it would dissociate into Na^+ and CH3COO^-. Then, the strong base we got from the weak acid combining with OH would then combine with Na^+ and become CH3COONa!!! So, pH of the solution would not be changed!
Buffer solution is made up of a weak acid and its conjugate base ❎
Buffer solution is made up of a weak acid and its salt ✅

[@pokemonjynx1019]

@@junaid6730 okay, so the salt neutralizes the base to maintain the pH, thanks for explaining

Isn't it the hydrogen ion (not hrydronium ion) which conjugate base consumes ?

Can't the 'H' Which you added and the added 'OH' react with each other?

[@jo-vd8no]

no (im not an expert), but im pretty sure H is to make something acidic whole OH is to make something basic. and itll just be weired if u put those 2 together.
