In acidic medium, oxidation action of potassium permanganate depends upon:
Correct answer: A. Mn7+
- A. Mn7+
- B. KMnO2+
- C. MnO2
- D. Mn1+
- E. Mn4+
Explanation
Equation for reduction of KMnO4 in acidic medium:8H+ + MnO4- + 5e- ----> Mn2+ + 4H2OHere in MnO4- the oxidation state of Mn is +7, and it is being reduced to Mn2+Therefore, it acts as an oxidising agent as Mn7+ can gain elections from the substance being oxidised and get reduced itself.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
