Answer 2

Explanation:

Given:

A cell is given consisting of two ions as follows:

\boxed{ \rm{Mg : {Mg}^{ + 2} \: | \: {Cu}^{ + 2} : Cu}}

Mg:Mg

+2

∣Cu

+2

:Cu

To find:

The correct statement/s :

(A) Mg is cathode

(B) The cell reaction is Mg + Cu2+ →Mg2+ + Cu

(C) Cu is cathode

(D) Cu is the oxidizing agent

Solution:

\begin{lgathered}\sf{Mg \rightarrow {Mg}^{ + 2} + 2e} \\ \sf{{Cu}^{ + 2} + 2e \rightarrow Cu}\end{lgathered}

Mg→Mg

+2

+2e

Cu

+2

+2e→Cu

So, cell reaction becomes:

\boxed{ \red{ \large{ \sf{Mg + {Cu}^{ + 2} \rightarrow{Mg}^{ + 2} + Cu} }}}

Mg+Cu

+2

→Mg

+2

+Cu

Here , Copper (Cu+2) acts as the oxidising agent.

Copper(Cu) is the cathode.

So, statements 2 , 3 and 4 are correct.
