Question

An Fe rod is dipped in CuSO, solution and kept for sometime

a)What happens to the colour of CuSO, solution?
b)What happens to the Fe rod? (oxidation/ reduction). Write the equation also.
c) What happens when a silver rod is dipped in CuSO, solution? Give reason.​

Answer 1

Explanation:

a) When an iron nail immersed in the solution of copper sulphate than iron displaces copper from the solution of copper sulphate because iron is more reactive than copper. Therefore copper sulphate solution colour changes from blue to pale green

b) Chemical reaction of iron nail with copper sulphate solution in water. Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal. ... Fe (s) + Cu2 + (aq) —→ Fe2+ (aq) + Cu (s).

c) When an iron rod is dipped in CuSO

4 solution, copper sulphate gets decomposed and brown layer of the copper is deposited on iron rod.
