How many atoms are in na2so4
Sodium sulfate is a typical electrostatically bonded ionic sulfate. The existence of free sulfate ions in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba or Pb salts: Na2SO4 + BaCl2 → 2 NaCl + BaSO4 Sodium sulfate is unreactive toward most oxidizing or reducing agents. At high temperatures, it c…
