Question

Which one of the follwing would be displaced from the solution of its salts b ly other three metals and why ?
(a) Mg
(b) Cu
(c) Ag
(d) Zn
​

Answer 1

Answer:

Ag metal would be displaced from the solution of its salt by Mg, Zn or Cu metals.

Among the given metals, the standard reduction potential for the half reaction Ag

+

+e

−

→Ag is maximum.

Hence, among the given metals (ions), Ag

+

ion has maximum strength as oxidising agent. Hence, Ag

+

ion gains an electron and other metals loses electron

Explanation:

please mark me as brainliest

Answer 2

Answer:agExplanation:according to reactivity series mg is highly reactive comparing to other three... helps....then zinc ..then copper...so ag will be displaced by all three hope this helps
