People remember this is just an acidic buffer there are basic buffers asw that operate same priniciples but some differences exist great vid very clear and concise info
Thanks, it makes sense now WHY there is a large reservoir of the acid and the base - having excess of the 2 components allows for change in pH to be buffered regardless of whether it is acid or the alkali that was added
Hello! thank you so much for this video, it's interesting, didactic and connected to reality! I have a question, I've seen that after preparing a solution some people adjust and measure its (final desired) pH before adding water. Why is that? Even if it is deionized water, wouldn't it change the pH to closer to 7? Does it depend on the quantity? I get that deionized water doesn't add ions to the solution, but I don't get how the volume of the solution works here... Is there a way of calculating how much water you can add without altering the pH? Thank you!
When we add OH to the buffer, it will make more A- right? So in my understanding, the equilibrium will shift to the left and make the solution more basic... While if we add H+ to the solution, the equilibrium will also shift to the left. So no matter what we add, we'll make more weak acid? Is that correct?
Great question! I think it's because the equilibrium of the weak acid is controlled by the proton concentration. But that's just a guess, I'm also trying to figure this out!
Am here to thank you soooo much!!! Ur wy of explaination is really great... perfect and clear... And thank you again for this video... and hope Good Luck for u.. :) ✨️
Why does OH- react with HA in the neutralization reaction and does not react with H3O+ (actually a stronger acid)? Plus, how can the pH still change a little bit if the reaction does not let the concentration of OH- or H+ to vary?
It gets always talked about the addition of a strong acid or strong base... my question would be how to calculate the ph with the addition of a weak acid? Lets say the addition of acetic acid to a phosphate buffer
This is the clearest explanation of buffers I’ve found so far and I’ve looked everywhere!
You can't imagine how difficult I thought this unit was. But this video made it so simple. Thank you man!!!

great vid very clear and concise info
This video was really helpful for me. For a long time I was confused of how exactly buffers work. You made it so clear. Thanks a lot!!
You totally save me from my lab report on buffer solution! Thanks
high school junior started crying in ap chem IVE BEEN SAVED THANK YOU
i wasn’t paying attention in class so thanks bro this really helped out 👍🏼

Fgyyo Edi s 😃😃😃
thank you for making this, got an exam tomorrow and i just now fully understood this topic 🤦♀️
The best explanation for buffers. Thank you so much!
My teacher needs to get fired
Thank you for very much, I was searching for a clear explanation about BUFFERS and found this video . This was really helpful
Awesome! All the other explanations of buffers out there neglected to explain exactly _why_ the A- has to have a Na attached to them.
Thank you so much for your help! I couldn’t wrap my head around buffers but you made it very simple and straightforward.
You've given me the clear explanation i have searching for
I swear, I've spent more than two weeks trying to understand, but now i did it. thank u sir.

Really very helpful video for basic understanding of how buffer work. Thanku you sir.

Omg..I was clueless and couldn't figure it out but after this video..I know ehat buffers are and how they work. Thank you so much!
thank you for your comprehensive explanation!
You explained this 1000x better than my teacher did
This is so helpful, thank you so much I better understand what that buffer system means.
very helpful simplest explanation of buffers ever ....thank u
Perfect clarification of buffers ever!!!
Easy to understand. Thanks so much!
Wow this was an amazing explanation thank you
Very nice explanation. Thank you, Sir.
ur goat bro, such a good video, THANK YOU
perfect, definitely the clearest explanation!! thxxx so much
One of the best explanations, thank you
Great video to explain how buffers work
finally understand what buffer mean and how it work thank you
Brilliantly explained. Thank you so much
Litterally owe u my first new born, tysm

Very helpful, thanks
4:10 But if the weak acid yields large amounts of its conjugate base, then why does that conjugate base not drastically affect the pH of the solution?
Great question! I think it's because the equilibrium of the weak acid is controlled by the proton concentration. But that's just a guess, I'm also trying to figure this out!
Very helpful and clear!
Great video man
Thank you so much sir your videos are really helpful for me 🙏

Nice work on this video😌
Yeah this is actually helpfull 😃
Good explanation
Thanks. Took me ages to make!
Thank you. Very helpful 😊
this is great !! thanks sm for the video !!
this vid is a real help
Extremely useful.
Glad you think so!
This is really clear.
Glad it helped. Tried to make it clear and step by step
Great video!
absolute OG, thanks fam

Thank you Sir
Fantastic job..
you just saved my grades

I have a question tho, instead of a weak acid and it’s salt, could you have a weak base and it’s salt
What is the purpose of salt in a buffer solution? Won't the acid dissociate and form its conjugate base itself?
helpful af
thanks really helpful
I finished a Master of Forensic Science program (two disciplines) and this was not simply put lol
Thanks
Ma shaa Allah 🌸🤍thank u
Tq 👏
very helpful ngl
really helpful
I'm glad you thought so!
god's gift to Earth
What happens to the excess sodium ions in solution at the end?
I thought you needed a weak acid and a weak base? why you used a strong conjugate base?
To understand how buffers work we'll add OH- to the solution already having HA
clear
HA = H+ and A- , here a- is conjugate base
HA doesn't completely dissociate as it's a weak acid .
I've just gotta say it looks like the solution is laughing. I will never look at HA solutions the same again 😭
Omg same 😭 😭
Wait if you added H+ why don't you just add weak base buffer to the unbuffered solution instead of just using HA and salt?
Great explanation!
So basically NaA is only there to provide A- for H+ added in
and that H+ forms bond with A- creating weak acid that doesn't increase pH very much
I was looking for a Brit guy to explain this , finally an accent that is not cringe to hear
ur cringe
A buffer solution can maintain the pH even when extra acid / base are added .
ty bruh
👏👏
this video must be from the gods
Fst viewrs
Awesome. Thanks for watching.
