Question

In each test tubes A, B, C and D, 2mL of solution of Al₂(SO₄), in water was filled. Clean pieces of zinc were placed in test tube A, clean iron nail was put in test tube B, silver (Ag) was placed in test tube C and a clean copper wire was placed in test tube D. 

Which of the following option (s) is/are correct about above experiment? 

A. Zinc is more reactive than aluminium 

B. Copper is more reactive than aluminium 

C. Zinc is more reactive than copper 

D. Zinc, iron, silver and copper are less reactive than aluminium

Answer 1

Zinc, Copper as well as silver are less reactive as compared to aluminium and hence cannot displace aluminium from its salt as they are placed below aluminium in activity series. 

So the correct answer is d. 

The activity series of metals is as follows:
