Chapter 19, Problem 82A
Interpretation Introduction

(a)

Interpretation:

The given redox reaction is to be balanced.

Concept introduction:

Oxidation number method to balance ionic equation involve:-

  • Assign the oxidation number to each element.
  • Check which element is oxidized and which element is reduced.
  • Check the change in oxidation number for the elements which are oxidized and reduced.
  • Balance the change in oxidation number by adjusting the coefficients in the equation.

Answer to Problem 82A

3P+2H2O+5HNO33H3PO4+5NO

Explanation of Solution

The given redox reaction is:

P+H2O+HNO3H3PO4+NO

Assigning the oxidation number-

P0+H2O+HN+5O3H3P+5O4+N+2O

The oxidation numbers of atoms shows that

P is oxidized and N is reduced.

Change in oxidation number of P=+5

Change in oxidation number of N=3

Thus adjusting the coefficients:

3P+H2O+5HNO33H3PO4+5NO

Adjusting the rest atoms:

3P+2H2O+5HNO33H3PO4+5NO

Answer to Problem 82A

2KClO3+4HClCl2+2ClO2+2H2O+2KCl

Explanation of Solution

The given redox reaction is:

KClO3+HClCl2+ClO2+H2O+KCl

Assigning the oxidation number-

KCl+5O3+HCl1Cl20+Cl+4O2+H2O+KCl1

The oxidation numbers of atoms shows that

Cl is oxidized and Cl is reduced.

Change in oxidation number of Cl=5+1+6=12

Change in oxidation number of Cl=15=6

Thus adjusting the coefficients:

KClO3+2HCl12Cl2+ClO2+H2O+KCl

Adjusting the rest atoms:

2KClO3+4HClCl2+2ClO2+2H2O+2KCl
