*Which is strongest oxidizing agent? Given E° for Fe³⁺ /Fe²⁺ =+0.77V, I₂ /I - = +0.54V, Cu²⁺ /Cu = +0.34V, Ag⁺ /Ag = +0.80V*

1️⃣ Fe³⁺
2️⃣ I₂
3️⃣ Cu²⁺
4️⃣ Ag⁺​

Answer 1

Explanation:

(4) is the correct answer

Answer 2

Given:

E° for Fe³⁺ /Fe²⁺ =+0.77V, I₂ /I - = +0.54V, Cu²⁺ /Cu = +0.34V, Ag⁺ /Ag = +0.80V

To find:

The strongest oxidising agent ?

1️⃣ Fe³⁺

2️⃣ I₂

3️⃣ Cu²⁺

4️⃣ Ag⁺

Solution:

• An oxidising agent is a substance which will oxidize other molecules and itself get reduced.

• So, with all the given potentials for the ions/molecules, we need to check which one has the highest reduction potential.

• The ion/molecule with the highest reduction potential will get strongly reduced to lower oxidation state and will help other substances to get oxidized to higher oxidation states.

• So, in the given options, we can see that conversion of Ag ion to Ag molecule has the highest reduction potential of +0.80 Volts.

• Hence, $Ag^{+}$ is the strongest oxidizing agent , because it has the highest tendency to become reduced.
