Titration curve question
« on: September 23, 2010, 08:57:59 AM »
Hi everyone,

For a weak acid whose pKa is 4.2, how do I find what the pH is at the point on the titration curve where the ratio of salt (A-) to acid (HA) is 2:1 ?

Thanks for your *delete me*

Thanks for the reply!

Would [A-] be 2 and [HA] be 1 for this problem?
