Question

When few pieces of iron are dropped into a blue solution of Coppersulphate, its blue colour slowly changes into light green and a reddish brown substance is formed
.a)State the characteristic of this reaction.
b)Write a word equation for the above reaction?
c)Identify the type of chemical reaction.

Answer 1

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.

Fe(s)+CuSO4 (aq)→FeSO4 +(aq)+Cu(s)
