Question

Give a chemical equation when iron nails put inside copper sulphate solution.

Answer 1

Fe+CuSO4=FeSO4+Cu
its balanced ^_^

Answer 2

When iron nail is put inside copper sulphate solution iron being more reactive than copper displaces copper from CuSO4 solution

REACTION: CuSo4+Fe ---> FeSO4+Cu

OBSERVATION:The copper displaced by iron in the reaction is visible as a pink-brown precipitate that usually forms on the unreacted mass of solid iron left over
