AIM

(i) To observe the action of Zn, Fe, Cu and Al metals on the following salt solutions :


(a) ZnSO4(aq.)


(b) FeSO4(aq.)


(c) CuSO4(aq.)


(d) Al2(SO4)3(aq.)


(ii) To arrange Zn, Fe, Cu and Al (metals) in the decreasing order of reactivity based on the above result.

 2

Why is there is a difference in reactivity of different metals?

 3

Which reaction is used to determine the relative reactivities of metals? Define the type of reaction.

 4

Name the most reactive & the least reactive metal.
