Explanation:
CH3COONa is the salt of a weak acid (acetic acid) and a strong base (sodium hydroxide).
The CH3COO- ions will react with water:
CH3COO-(aq) + H2O(aq) CH3COOH(aq) + OH- (aq)
The CH3COO- ion is a Bronsted-Lowry base. The solution will be basic.
Kb = [CH3COOH] x[OH-] = 5.6 x 10-10
[CH3COO-]
Any anion derived from a weak acid will be a weak base
