Buffer Solutions Explained Simply: What is a Buffer and How Does a Buffer Solution Work?

In this video I will give you a simple and easy to follow explanation of what exactly a buffer solution is, how a buffer solution is made and how a buffer solution works to keep pH constant.

[@ellastenslunde1307]

This is the clearest explanation of buffers I’ve found so far and I’ve looked everywhere!

[@TheQueenIsWatching6517]

You can't imagine how difficult I thought this unit was. But this video made it so simple. Thank you man!!!

[@mirzunayedali1724]

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

[@mukhtar2759]

I swear, I've spent more than two weeks trying to understand, but now i did it. thank u sir.

[@marinewaves3]

The best explanation for buffers. Thank you so much!

You totally save me from my lab report on buffer solution! Thanks

[@divya.sinha.]

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!!

[@francischiemerie947]

You've given me the clear explanation i have searching for

[@jodistamand8887]

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!

[@sophieguardian8210]

Thank you so much for your help! I couldn’t wrap my head around buffers but you made it very simple and straightforward.

[@joe____]

Awesome! All the other explanations of buffers out there neglected to explain exactly _why_ the A- has to have a Na attached to them.

[@thanurirajapakshe3455]

Thank you for very much, I was searching for a clear explanation about BUFFERS and found this video . This was really helpful

[@dawndreecinco6324]

This is so helpful, thank you so much I better understand what that buffer system means.

[@drs1065]

finally understand what buffer mean and how it work thank you

Thank you so much sir your videos are really helpful for me 🙏

[@gilmagunakanthi7842]

So understandable. Thank you so much.❤

Easy to understand. Thanks so much!

[@zayanmirza877]

My teacher needs to get fired

[@angieg7257]

Great explanation!

[@avionyellow1712]

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

[@hoofawu8488]

ur goat bro, such a good video, THANK YOU

[@franknjenga7284]

This video is extremely helpful

[@luizabrito1522]

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!

Good explanation

[@TheCompleteGuide1]

Thanks. Took me ages to make!

[@hisyamhasbi8257]

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?

[@bobofaggi]

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?

[@Et_sapien]

clear

[@rubina4578]

Ma shaa Allah 🌸🤍thank u

[@TheStefProff]

ty bruh

[@bjornbuckley]

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?

[@Overthought7]

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!

[@hudsonhoneybone5207]

I have a question tho, instead of a weak acid and it’s salt, could you have a weak base and it’s salt

[@pianellrielly9803]

What happens to the excess sodium ions in solution at the end?

[@esmfamil5086]

What is the purpose of salt in a buffer solution? Won't the acid dissociate and form its conjugate base itself?

[@patrickstar7693]

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

[@farahbashir8900]

👏👏

[@azizabaptiste5358]

I thought you needed a weak acid and a weak base? why you used a strong conjugate base?

[@beartheburn3863]

HA = H+ and A- , here a- is conjugate base
HA doesn't completely dissociate as it's a weak acid .

[@beartheburn3863]

To understand how buffers work we'll add OH- to the solution already having HA

[@techmcu]

Fst viewrs

[@TheCompleteGuide1]

Awesome. Thanks for watching.

[@beartheburn3863]

A buffer solution can maintain the pH even when extra acid / base are added .

[@adityaadit2004]

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?

[@MedusaMrigesh]

Great explanation!

[@ThomasChesterson]

So basically NaA is only there to provide A- for H+ added in

[@ThomasChesterson]

and that H+ forms bond with A- creating weak acid that doesn't increase pH very much

[@abdulali_jm]

منووووور

[@midnightstorm4290]

this video must be from the gods

[@orca._.]

I've just gotta say it looks like the solution is laughing. I will never look at HA solutions the same again 😭

[@jayantpandey3628]

I was looking for a Brit guy to explain this , finally an accent that is not cringe to hear

HA - weak acid
