Question

In the given reaction,

Copper metal, $Cu (s)$ is oxidised to $Cu ^{2+}(a q)$, while $Ag ^{+}(a q)$ is reduced to silver metal, Ag $(s)$ then the equilibrium greatly lies in favour of

• A. $Ag ^{+}(s)$ and $Cu ^{2+}(a q)$
• B. $Ag ^{+}(a q)$ and $Cu ^{2+}(s)$
• C. $Ag (s)$ and $Cu ^{2+}(a q)$
• D. $Cu ^{2+}(a q)$ and $Ag (s)$

Answer 1

Answer: (D)

Copper being more reactive than silver, can displace silver from its salt solution but opposite is not possible. Thus, equilibrium lies towards right hand side, i.e. in favour of $Cu ^{2+}$ and Ag.
