Now, for B, we proceed as follows: KC 2 H 3 O 2 is the salt of a weak acid (HC 2 H 3 O 2) and a strong base (KOH).The salt will hydrolyze as follows: C 2 H 3 O 2-+ H 2 O ==> HC 2 H 3 O 2 + OH-. And to find the [OH-], and thus the pOH and then the pH, we need either the Kb for C 2 H 3 O 2 - or the Ka for HC 2 H 3 O 2 (acetic …
