A solution of Na₂SO₄ is:
Correct answer: C. Neutral
- A. Basic
- B. Acidic
- C. Neutral
- D. Not predictable
Explanation
Sodium sulfate (Na₂SO₄) is a salt formed from a strong acid (H₂SO₄) and a strong base (NaOH). Neither of its ions will hydrolyze water, so the resulting solution is neutral.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
