What Is The PH Of A Sodium Sulfate Solution?

Sodium sulfate is a salt composed of sodium cations (Na+) and sulfate anions (SO42-). When it dissolves in water, it dissociates into its constituent ions. Neither the sodium cation nor the sulfate anion hydrolyzes in water, so they do not affect the pH of the solution.

Therefore, the pH of a sodium sulfate solution will depend on any other acid or base present in the solution. If no other acidic or basic species are present, the pH of a sodium sulfate solution will be neutral at 7.0.
