Interpretation Introduction

Interpretation:

The values of a, b, c, d, and e in the given diagram are to be determined.

Concept Introduction:

Oxidation is the addition of an electronegative element or the removal of an electropositive element in a chemical reaction.

Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction.

A chemical reaction in which oxidation process and reduction process take place simultaneously is called a redox reaction.

An oxidizing agent is a substance that has the capacity to oxidize other substances and get reduced in a chemical reaction.

A reducing agent is a substance that has the capacity to reduce other substances and get oxidized in a chemical reaction.

An electrochemical cell is also known as a galvanic or voltaic cell.

An electrochemical cell is a type of battery that converts chemical energy into electrical energy.

An electrochemical cell contains two half-cells.

Oxidation occurs in one half-cell and reduction in the other half-cell.

Oxidation occurs at the anode and reduction occurs at the cathode.

Explanation of Solution

An electrochemical cell contains two half-cells. Oxidation occurs in one half-cell and reduction in the other half-cell. Oxidation occurs at the anode and reduction occurs at the cathode. Therefore, the value of (a)Cathodeand (b)anode.

Redox reaction in an electrochemical cell is as:

Sn half-cell reaction occurs as oxidation at the anode.

Sn(s)Sn2+(aq)+2e

Therefore, the value of (c)is Sn2+ ions
