Question

Kmn04 oxidation state in acidic medium

Answer 1

Answer:

The oxidation state of KMnO₄ in acidic medium will be +2

Explanation:

When we add KMnO₄ in acidic medium it dissociates into its ions K⁺ and MnO₄⁻ .

As the acidity depends on MnO₄⁻, we neglect the potassium ion here:

Mn0₄⁻ in acidic medium

When we add potassium permanganate into acidic medium it dissociates into potassium and permangante ions. permanganate ions then reacts with available protons and electons in the acidic medium and Mn⁺² and water will produce as product.

Reaction

MnO₄⁻ + 8H⁺ + 5e⁻    →  Mn⁺² + 4H₂O
