Question

c) Which reagents are not useful to determine the relative reactivities of all metals? :Answer
​

Answer 1

Answer:

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

ZnSO4 (aq)

FeSO4 (aq)

CuSO4 (aq)

Al2(SO4)3 (aq)

Arrange Zn, Fe, Cu and Al metals in the decreasing order of reactivity based on the above results.

The Theory

Metals are elements and are good conductors of heat and electricity. Most metals are electropositive in nature and the metal atoms lose electrons in chemical reactions to form cations. The more reactive a metal, the greater tendency it has to form a positive ion in a chemical reaction.
