Chapter 17, Problem 19QAP

Interpretation Introduction

(a)

Interpretation:

The stronger oxidizing agent needs to be identified between the following pair of oxidizing agents.

Cr or Cd

Concept introduction:

Oxidizing agent is the species which oxides others and itself gets reduced in a chemical reaction. Thus, the more positive the standard potential more strongly the species can undergo reduction and act as a strong oxidizing agent.

Interpretation Introduction

(b)

Interpretation:

The stronger oxidizing agent needs to be identified between the following pair of oxidizing agents.

I- or Br-

Concept introduction:

Oxidizing agent is the species which oxides others and itself gets reduced in a chemical reaction. Thus, the more positive the standard potential more strongly the species can undergo reduction and act as a strong oxidizing agent.

Interpretation Introduction

(c)

Interpretation:

The stronger oxidizing agent needs to be identified between the following pair of oxidizing agents.

OH- or NO₂ - (basic solution)

Concept introduction:

Oxidizing agent is the species which oxides others and itself gets reduced in a chemical reaction. Thus, the more positive the standard potential more strongly the species can undergo reduction and act as a strong oxidizing agent.

Interpretation Introduction

(d)

Interpretation:

The stronger oxidizing agent needs to be identified between the following pair of oxidizing agents.

NO in acidic solution or NO in basic solution

Concept introduction:

Oxidizing agent is the species which oxides others and itself gets reduced in a chemical reaction. Thus, the more positive the standard potential more strongly the species can undergo reduction and act as a strong oxidizing agent.
