The correct graph which represents the concentration of metal ions in the given galvanic cell has to be identified from the given graphs. 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 a redox reaction, 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.

Interpretation Introduction

Interpretation:

The correct graph which represents the concentration of metal ions in the given galvanic cell has to be identified from the given graphs.

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 a redox reaction, 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.
