Reactions in which Sodium sulfite is involved

  • Na2SO3 + H2SO4 -> Na2SO4 + H2SO3
  • 2NaOH + SO2 -> Na2SO3 + H2O
  • {M}2O + {X}O2 -> {M}2{X}O3 , where M = Na K Li Rb Cs; X = C S Si
  • 2NaI + 2CuSO4 + Na2SO3 + H2O -> 2CuI"|v" + 2Na2SO4 + H2SO4
  • H2{X} + 2{M}OH = {M}2{X} + 2H2O , where X = SO4 SO3; M = Li Na K Rb
