Homework Statement



Determine the pH of0.15 M solution of sodium acetate, ka = 1.8 x 10^-5




The Attempt at a Solution



Since there are no hydrogen ions that dissolve from sodium acetate, would I use the pH of water =7.0? Is the pH of water even affected by sodium acetate?

No.

Yes.

Acetate anion is a weak base (conjugate base of acetic acid).

OK, so the OH concentration can be found by this reaction

C2H3O2-+H2O <-> C2H3OOH + OH-?
