The equation FeSO4 + 3Na2S2O3 -> 3Na2SO4 + Fe2(S2O3)3

  1. Detailed information about the reaction FeSO4 + 3Na2S2O3 -> 3Na2SO4 + Fe2(S2O3)3:

The above chemical equation represents the reaction between Iron (II) Sulfate (FeSO4) and Sodium Thiosulfate (Na2S2O3) to form Sodium Sulfate (Na2SO4) and Iron (III) Thiocomplex (Fe2(S2O3)3).

  1. Reaction conditions:

The condition for the chemical reaction to occur is that both reactants, FeSO4 and Na2S2O3, need to exist in solution form in a humid environment.

  1. Reaction process:

FeSO4 reacts with Na2S2O3 to form Na2SO4 and Fe2(S2O3)3. This reaction is a redox reaction, in which FeSO4 is oxidized from an oxidation state of +2 to +3, while Na2S2O3 is reduced from an oxidation state of +6 to +4.

  1. Observed phenomena:

During the reaction process, the observable phenomenon is the change of solution color. Initially, the FeSO4 solution has a light blue color, when reacting with Na2S2O3, the solution changes to the characteristic brown-yellow color of Fe2(S2O3)3.
