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!!!!!!!!!!

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.

@dikshitkapil4686 4 года назад

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?

Awesome. Thank you.

It is really helpful thank you!

@pickaxingoneuropa8457 3 года назад

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!

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

@cesaryescas9336 3 года назад

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

@adrianparvez Год назад

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