When Iron is added to blue Copper (II) sulphate solution, the solution turns light green and a brown solid is precipitated.
a) Identify the type of reaction described above.
b)Explain the observations made

Answers

a)Displacement reactions
b)Iron is more reactive than copper, it therefore displaces copper ions from Copper (II) sulphate to form Iron (II) ions which are light green.Copper ions are reduced to copper metal which precipitates out.
