Question

what happens when following metals are added to CuSO4 solution. Write the colour change involved and also write the chemical equation.
(i) Cu
(ii) Al
(iii)Fe
(iv)Zn​

Answer 1

Explanation:

when zinc metal is added to a solution of copper sulphate (cuso4), the blue colour of the letter change to colourless as zinc sulphate (znso4)is formed in the displacement reaction zinc being more active metal than copper displaces its a form of zinc sulphate as shown below-zn(s) + cuso4(aq)-znso4(aq)+cu(s)
