When sodium acetate dissolves in water the resulting pH is above 7. This is because Sodium ion reacts with water to produce hydroxide ions. none of these answers Acetate ion reacts with hydroxide ions to produce excess protons. Sodium ion is the cation of a strong base and acetate is the anion of a weak acid.
