Common chemical reactions of Na2SO6
3.1 Reaction with strong acids such as HCl to produce sodium chloride, sulfur, and water:
Na2SO4 + 2HCl -> 2NaCl + H2SO4 -
Synthesis of Na2SO6
4.1 Laboratory synthesis of Na2SO6: Sodium sulfate can be synthesized from sodium hydroxide and sulfuric acid:
2NaOH + H2SO4 -> Na2SO4 + 2H2O
4.2 Industrial synthesis of Na2SO6: On an industrial scale, sodium sulfate is usually produced by absorbing SO2 gas into a solution of sodium hydroxide:
SO2 + 2NaOH -> Na2SO3 + H2O
Na2SO3 + O2 -> Na2SO4
