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.
