what happens when iron filings are dipped into copper sulphate solution? give a word equation to representa the reaction.

copper sulphate + Iron = Iron sulphate + copper

CuSO₄ + Fe = FeSO₄ + Cu

iron fillings,when dipped in  copper sulphate solution turns brown & the solution  turns pale  green  due  to the formation of iron sulphate solution.

iron + copper sulphate =iron sulphate + copper

Displacment reaction happens,because iron is a more reactive metel than copper.So you get

iron sulphate and copper.
