pH and pKa relationship for buffers | Chemistry | Khan Academy

[@garrettramos4044]

This was GREAT! I couldn't wrap my head around how to manipulate the equation to find the ratio of base to acid. All the other info I saw kept using examples with "live" figures. You explaining it without any specific numbers involved made it so much easier to see the relationships and follow the concepts. THANKS!!!!!!!!!!

Very helpful for my biochem exam 1 thanks

[@chemiflask7692]

That is a cute voice folks

[@mitsu_kyri]

Oh wow, this makes so much sense now! I always had such a hard time remembering if pH>pka would protonate or deprotonate a molecule and this suddenly helped make things click.

I really like the girl i find myself listening more!

Afaik , the concetration of pure water in 55.55M. so why did you avaoid that in 1:23

[@thomaskosten8113]

This finally helped me understand the HH equation thank you!!!

[@shambhaviacharya5425]

Why do all the teachers on this channel stutter it’s really hard for students who have concentration problems.

[@regularsizedpanda]

why doesn't the android app have these new videos?

[@vinzky89]

Thank you so muchhhhhh

[@jenniferfox8382]

These were so much better when Khan was explaining things. Every other video by anyone else is just a mess.

[@dikshitkapil4686]

I have a question here . How is the buffering related to the ph ? Is it that when HA= A- then the ph-pka is 0 and the buffering capacity is maximum?

[@XxXanime03XxX]

What happened to the other guy???????

[@pickaxingoneuropa8457]

Thank You for all your help! This MAKES sense- so like 2 over 1- so 2 is greater than 1. so if A- is the numerator and HA is the denominator THEN A- is greater than the weak acid. OH THANK YOU THANK YOU THANK YOU! You ARE A GENIUS!

[@inesguett8126]

Can someone tell me what ph is like not the meaning but the ph of what

[@cesaryescas9336]

pH is saying in English terms -log is the p in pH, and H is concentration of H3O+ a.k.a hydronium.

[@adrianparvez]

In this case, she's talking about the pH of the buffer solution

[@husseinali-ei6ft]

Mmmmmm very good

[@ed_dytv7011]

Traduction in arabic please(sous titre youtube)
