In which solution (acidic, basic, neutral water, or doesn't matter) is sodium acetate most soluble?

acidic solution
Basic solution
neutral
doesn't matter

I already tried basic solution and got it wrong.

The acetate ion is hydrolyzed to give
C2H3O2^- + HOH ==> HC2H3O2 + OH^-
So adding acid will neutralize the OH^- on the right and make the reaction shift to the right. I think an acid solution is the correct answer.
