I need help solving this problem
Acetic acid has a pka of 4.8. If you are making up a concentrated stock solution of 1M Sodium acetate buffer at pH 4.8, starting with acetic acid, how many ml of 10N NaOH will you have to add?
first 10N NaOH is the same thing as 10M right, I never learned those units and don't know what they are.
This is the equation that I came up with for the reaction
CH3COOH + NaOH --> CH3COO- + H2O
I really don't know how to go about doing this problem, I am thinking that i need to use the Henderson-Hasselbalch equation which will tell me the concentration of the acetic acid. Can some one point me in the right direction because i really don't know what to do after that.
Thanks
