Chapter 17, Problem 17.110CHP

(a)

Interpretation Introduction

Interpretation:

The balanced equation for the overall cell reaction has to be written.

(b)

Interpretation Introduction

Interpretation:

The oxidizing agent and reducing agent has to be given.

Concept Introduction:

Oxidizing agent:

An oxidizing agent or oxidant is a substance that gains electrons and gets reduced in a chemical reaction.  An oxidizing agent is also called as electron acceptor.

Reducing agent:

A reducing agent or reductant is a substance that loses electrons and gets oxidized in a chemical reaction.  A reducing agent is also called as electron donor.

(c)

Interpretation Introduction

Interpretation:

The standard cell potential has to be calculated.

Concept Introduction:

Cell potential (EMF):

The maximum potential difference between two electrodes of voltaic cell is known as cell potential.

If standard reduction potentials of electrodes are known, the cell potential (EMF) is given by,

${\text{E}}_{\text{cell}}\text{=}{\text{E}}_{\text{cathode}}{\text{-E}}_{\text{anode}}$

Where,

$\begin{array}{l}{\text{E}}_{\text{cathode}}\text{is}\text{the}\text{reduction}\text{half}\text{cell potential}\\ {\text{E}}_{\text{anode}}\text{is}\text{the}\text{oxidation}\text{half}\text{cell potential}\end{array}$
