1.	A student added a piece of zinc metal to four test-tubes l, ll, lll, IV which respectively contain aqueous solution of alurninium sulphate, zinc sulphate, ferrous sulphate and copper sulphate. In which solution the reaction will take place.
Answer» The reaction will take place in solution- III and IV. Zn will react with ferrous sulphate and copper sulphate. Zn + CuSO₄ → ZnSO₄ + Cu : Zn > Cu Zn + FeSO₄ → ZnSO₄+ Fe : Zn > Fe
