The equation FeSO4 + Na2S2O4 -> Na2SO4 + Fe2(S2O4)3

Detailed information about the equation:

• FeSO₄ (Iron(II) sulfate) and Na₂S₂O₄ (Sodium dithionite) react with each other to form Na₂SO₄ (Sodium sulfate) and Fe₂(S₂O₄)₃ (Iron(III) dithionite).
• This reaction is a redox reaction. FeSO₄ is oxidized from oxidation state II to oxidation state III, while Na₂S₂O₄ is reduced from oxidation state +6 to oxidation state +4.

Reaction conditions: The reaction occurs at room temperature and standard pressure.

Reaction process: First, you will need to prepare a solution of FeSO₄ and a solution of Na₂S₂O₄. When you mix these two solutions together, the reaction will start to occur, producing Na₂SO₄ and Fe₂(S₂O₄)₃.

Occurring phenomena: The initial solution is blue (due to FeSO₄) will turn to reddish-brown when Fe₂(S₂O₄)₃ is formed. Additionally, there may be a release of heat, creating a warm sensation when you touch the reaction container.
