Question

An electrochemical cell has the following standard cell notation.

Mg(s) | Mg^2+ (aq) || Aq^+(aq) | Aq(s)

Write the balanced oxidation and reduction half reactions, labeling the oxidation reaction and the reduction reaction.

Answer 1

Step-by-step explanation:

The given following standard cell notation.

Mg(s) | Mg^2+ (aq) || Aq^+(aq) | Aq(s)

Oxidation:

`Mg(s)\rightarrow Mg^(2+)+2e^-`....(1)

Magnesium metal by loosing 2 electrons is getting converted into magnesium cation. Hence, getting oxidized

Reduction:

`Ag^+(aq)+1e^-\rightarrow Ag(s)`...(2)

Silver ion by gaining 1 electrons is getting converted into silver metal. Hence, getting reduced.

Overall redox reaction: (1)+2 × (2)

`Mg(s)+2Ag^+(aq)\rightarrow Mg^(2+)+2Ag(s)`
