AIM : To observe the action of Zn,Fe,Cu and Al metals on their Sulphate solution.
Arrange Zn, Fe,Cu,Al metals in the decreasing order of their reactivity.
APPRATUS REQUIRED: Testubes, testube stand.
CHEMICALS REQUIRED: Zn, Fe,Cu,Al metals, Copper Sulphate,Zinc Sulphate,
Ferrous Sulphate and Aluminium Sulphate solution.
PROCEDURE Surface of the given metals were cleaned with the help of sand paper.
a) 10ml each of ZnSO4,FeSO4,CuSO4 solution was taken in three testubes. A small piece of Aluminium
was put in each of the testube. Surface of the metal and the colour of the solutions were observed.
b) 10ml each of Al2(SO4)3,FeSO4,CuSO4 solution was taken in three testubes. A small piece of Zinc
was put in each of the testube. Surface of the metal and the colour of the solutions were observed.
c) 10ml each of Al2(SO4)3, ZnSO4 ,CuSO4 solution was taken in three testubes. A small piece of Iron
was put in each of the testube. Surface of the metal and the colour of the solutions were observed.
d) 10ml each of Al2(SO4)3, ZnSO4, FeSO4 solution was taken in three testubes. A small piece of Copper
was put in each of the testube. Surface of the metal and the colour of the solutions were observed.
