1.	(a) Explain electrochemical series. (b) Can we store 1M `CuSO_(4)` solution in zinc vessel or not, why ?
Answer» (a) For Answer, Consult Section 7. (b) No, it is not possible. Zinc `(E^(@)=-0.76V)` will reduce `Ca^(2+)` ions `(E^(@)=+0.34V)` by taking part in the displacement reaction. `Zn(s)+Cu^(2+)(aq) to Zn^(2+)(aq)+Cu(s)`
