The maximum oxidation number that manganese can exhibit in its compounds is to be determined from the given option. Concept introduction: The substance that easily be reduced in a reaction is represented as an oxidizing agent. For metal cations, a good oxidizing agent can be determined by the standard reduction potential values. Half-cell: In the electrochemical cell, both oxidation and reduction occurs. Oxidation occurs at the anode and reduction occurs at the cathode Standard electrode potential of cell is defined as the difference of reduction potential at cathode to the reduction potential at anode. For the cathode and anode reactions, the values are taken from the standard reduction potential table. The standard cell potential is calculated by taking the difference between the standard reduction potential values of the cathode and anode. E cell 0 = E cathode 0 − E anode 0

Interpretation Introduction

Interpretation: The maximum oxidation number that manganese can exhibit in its compounds is to be determined from the given option.

Concept introduction:

The substance that easily be reduced in a reaction is represented as an oxidizing agent. For metal cations, a good oxidizing agent can be determined by the standard reduction potential values.

Half-cell: In the electrochemical cell, both oxidation and reduction occurs. Oxidation occurs at the anode and reduction occurs at the cathode

Standard electrode potential of cell is defined as the difference of reduction potential at cathode to the reduction potential at anode.

For the cathode and anode reactions, the values are taken from the standard reduction potential table. The standard cell potential is calculated by taking the difference between the standard reduction potential values of the cathode and anode.

Ecell0 = Ecathode0 − Eanode0
