The equation Fe + 2CuSO4 -> FeSO4 + 2Cu

Detailed information about the equation Fe + 2CuSO₄ -> FeSO₄ + 2Cu:
The above chemical equation describes the chemical reaction between iron (Fe) and copper sulphate (CuSO₄) to form iron sulphate (FeSO₄) and copper (Cu). This is a metal replacement reaction, in which iron, having a higher valency than copper, replaces copper in the compound copper sulphate.

Reaction conditions:
The reaction occurs when iron comes into contact with a solution of copper sulphate. Room temperature is sufficient for the reaction to take place.

Reaction process:
When iron comes into contact with a solution of copper sulphate, iron ions will replace copper ions in the compound copper sulphate, forming iron sulphate and copper. Iron is oxidized to iron(II) while copper is reduced from copper(II) to copper.

Phenomena that occur:
When iron is added to a solution of copper sulphate, iron will gradually dissolve and brown-red particles of copper will appear on the surface of the iron. The blue solution slowly changes to a lighter blue or colorless due to the decrease in the amount of copper sulphate.
