Question

What happens when a piece of silver metal is added to copper sulfate solution?

• A. Silver sulfate is formed
• B. Silver displaces copper sulfate
• C. Oxygen gas is evolved
• D. No reaction

Answer 1

The correct option is D

No reaction

The explanation for the correct option:

D. No reaction

The reaction of Silver with Copper sulfate:

• There will be no reaction when silver reacts with copper sulfate solution $\left({\mathrm{CuSO}}_4\right)$ as reactivity of silver is less than that of copper, as per the reactivity series.
• In the reactivity series, Silver$\left(\mathrm{Ag}\right)$ lies below Copper $\left(\mathrm{Cu}\right)$, thus it will not displace copper from its solution. As a result, there will be no displacement reaction.

$\mathrm{Ag}\left(\mathrm{s}\right)+{\mathrm{CuSO}}_4\left(\mathrm{aq}\right)\to \mathrm{No}\mathrm{reaction}$

Explanation for incorrect options:

Since there is no reaction between silver with copper sulfate. Thus, options A, B, and C stand incorrect.

Hence, option D i.e. No reaction is the correct option.
