Question

A buffer solution is prepared by adding 0.10 L of 2.0 M acetic acid solution to 0.10 L of a 1.0 M solution of sodium hydroxide. Compute the hydrogen ion concentration of the buffer solution.

Answer 1

Hey scrubby, if you haven't already please read through my response to your previous question. Thanks. :)

Answer 2

ok if this is done with assumption that acetic acid dissociates completely you first need to write chemical reaction equation and then calculate amount of each chemical you have in moles from given concentration and volumes, then you need to see which one is limiting reagent, (in your case NaOH) and then subtract amount of limiting reagent from more abundant reagent to get amount of more abundant reagent which remains after reaction (in your case 0,1moles of AcH) and then add together volumes and calculate concentration, so in your case result is 0,5 M. if you are unclear about any step just say and ill try to clear it out, hope this helps you.
