Reactions in which Sodium stannate is involved

  • Sn + 2NaOH + 4H2O "100^oC"--> Na2[Sn(OH)6] + 2H2
  • SnO2 + 2NaOH + 2H2O "60-70^oC"--> Na2[Sn(OH)6]
  • Na2[Sn(OH)6] "140^oC"--> Na2SnO3 + 3H2O
  • Na2[Sn(OH)6] "900^oC"--> Na2O + SnO2 + 3H2O
  • Na2[Sn(OH)6] + 2H{X} -> SnO2"|v" + 2Na{X} + 4H2O , where X = Cl F Br I NO3
