Step 1

Reaction taking place at the equivalence point is given. CH3COO- from CH3COOK (salt) reacts with water to give acetic acid and OH-. The base dissociation constant is determined from the given equation.

Step 2

At equivalence point, number of moles of salt formed will be equal to the number of moles acetic acid reacted. Number of moles of acetic acid can be determined from the given formula.

Step 3

Since the number of moles of acid and base are equal at equivalence point, the number of moles of KOH reacted will b...
