QAIPM-2012-Ch-1625: NEET 2012 Chemistry - Class 12 AIPM-2012-Ch-1625 Solution: Standard reduction potentials of the half reactions are given…

Standard reduction potentials of the half reactions are given below:

F_2(g) + 2e^- \rightarrow 2F^-(aq); E^\circ = +2.85\ \text{V}

Cl_2(g) + 2e^- \rightarrow 2Cl^-(aq); E^\circ = +1.36\ \text{V}

Br_2(l) + 2e^- \rightarrow 2Br^-(aq); E^\circ = +1.06\ \text{V}

I_2(s) + 2e^- \rightarrow 2I^-(aq); E^\circ = +0.53\ \text{V}

The strongest oxidising and reducing agents respectively are

F_2

and

I^-

Br_2

and

Cl^-

Cl_2

and

Br^-

Cl_2

and

I_2

Multiple Choice Options

A F 2 and I $-$ _
B Br 2 and Cl $-$ _
C Cl 2 and Br $-$ _
D Cl 2 and I 2

Step-by-Step Verified Solution

Higher the value of reduction potential higher will be the oxidising power whereas the lower the value of reduction potential higher will be the reducing power.
