Sodium sulfate - Wikipedia

Sodium sulfate is a typical electrostatically bonded ionic sulfate. The existence of free sulfate in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba 2+ or Pb 2+ salts: Na 2 SO 4 + BaCl 2 → 2 NaCl + BaSO 4. Sodium sulfate is unreactive toward most oxidizing or reducing agents.
