Reactions in which Potassium thiosulfate is involved

  • Ag{X}"`(s)`" + 2{M}2S2O3"`(aq)`" -> {M}3[Ag(S2O3)2]"`(aq)`" + {M}{X}"`(aq)`" , where X = Br Cl I; M = Na K
  • K2SO3 + S "100^oC"--> K2SO3S
  • 6KOH + 2H2S + 4SO2 -> 3K2SO3S + 5H2O
  • 4K2SO3S ">430^oC"--> 3K2SO4 + K2S5
  • K2SO3S + 2H{X} -> 2K{X} + SO2"|^" + S"|v" + H2O , where X = Cl F Br I
