(a)

Interpretation Introduction

Interpretation:

The following half reaction in acidic medium should be balanced.

  ${\text{I}}_2(\text{s})\to {\text{I}}^{-}\text{(aq)}$

Concept Introduction:

A half reaction for a redox chemical reaction shows the half component of a given redox reaction which means it will show the oxidation and reduction of half reactions separately.

In oxidation, loss of electrons occurs whereas in reduction, gain of electrons occurs.

A balanced reaction is a reaction in which number of atoms and charges should be equal on both reactant as well as on product sides.

Interpretation Introduction

(b)

Interpretation:

The following half reaction in acidic medium should be balanced.

  ${\text{MnO}}_4^{-}\text{(aq)}\stackrel{}{\to }{\text{Mn}}^{\text{2+}}\text{(aq)}$

Concept Introduction:

A half reaction for a redox chemical reaction shows the half component of a given redox reaction which means it will show the oxidation and reduction of half reactions separately.

In oxidation, loss of electrons occurs whereas in reduction, gain of electrons occurs.

A balanced reaction is a reaction in which number of atoms and charges should be equal on both reactant as well as on product side.

Interpretation Introduction

(c)

Interpretation:

The following half reaction in acidic medium should be balanced.

  ${\text{Br}}_2\text{(l)}\stackrel{}{\to }{\text{BrO}}_3^{-}\text{(aq)}$

Concept Introduction:

A half reaction for a redox chemical reaction shows the half component of a given redox reaction which means it will show the oxidation and reduction of half reactions separately.

A balanced reaction is a reaction in which number of atoms and charges should be equal on both reactant as well as on product side.

Interpretation Introduction

(d)
