Question

assertion(a):iron displaces copper from copper sulphate solution reason(r): a less reactive metal displaces highly reactive metal from its salt solution A) both a and r are true and r is correct explanation of A. B)both a and r are true and R is not correct explanation of A C)A is correct and R is incorrect. D) A is incorrect and R is correct​

Answer 1

Answer:

False

Answer

A less reactive metal cannot replace a more reactive metal from its salt solution in water.

In the reactivity series of metals in an arrangement of metals in the order of their decreasing reactivities. A more reactive metal can displace a less reactive metal from a solution of its salt.

For example:-CuSO

4

+Fe→FeSO

4

+Cu

Answer 2

Answer:

(C)A is correct and R is incorrect.

Explanation:

Since, Iron is more reactive than Copper, Yes it can displace copper from its salt solution.

But Reason is incorrect because a less reactive metal cannot displace a more reactive metal from it solution.
