Expert Answer
Some chemical reactions are characterised by a change in the colour of the reactants.
Example: A few pieces of iron are added into a blue-coloured copper sulphate solution; the blue colour of copper sulphate fades and eventually turns into light green due to the formation of ferrous sulphate.
Fe + CuSO4 → FeSO4 + Cu
