(a)

Interpretation Introduction

Interpretation:

The loss of electrons needs to be classified as oxidation or reduction.

Concept Introduction:

In a redox reaction both oxidation and reduction take place simultaneously. Oxidation takes place by loss of electrons and reduction takes place by gain of electrons. The oxidation state of a species increases on oxidation and decreases on reduction. In a reaction, one of the reactants get oxidized and 1 gets reduced, this is known as a redox reaction.

Interpretation Introduction

(b)

Interpretation:

The reaction of an oxidizing agent needs to be classified as oxidation or reduction.

Concept Introduction:

In a redox reaction both oxidation and reduction take place simultaneously. Oxidation takes place by loss of electrons and reduction takes place by gain of electrons. The oxidation state of a species increases on oxidation and decreases on reduction. When in reaction 1, one of the reactants get oxidized and 1 gets reduced, this is known as a redox reaction. The species that oxidizes others and itself gets reduced is known as an oxidizing agent.

Interpretation Introduction

(c)

Interpretation:

The given reaction needs to be classified as oxidation or reduction:

  ${\text{O}}_{\text{2}}\left(g\right)\to {\text{OH}}^{-}\left(aq\right)$

Concept Introduction:

In a redox reaction both oxidation and reduction take place simultaneously. Oxidation takes place by loss of electrons and reduction takes place by gain of electrons. The oxidation state of a species increases on oxidation and decreases on reduction. In a reaction, oneof the reactants get oxidized and one gets reduced, this is known as a redox reaction. The species that oxidizes others and itself gets reduced is known as an oxidizing agent.

Interpretation Introduction

(d)

Interpretation:

The given reaction needs to be classified as oxidation or reduction:

  ${\text{Br}}_{\text{2}}\left(l\right)\to 2{\text{Br}}^{-}\left(aq\right)$

Concept Introduction:

In a redox reaction both oxidation and reduction take place simultaneously. Oxidation takes place by loss of electrons and reduction takes place by gain of electrons. The oxidation state of a species increases on oxidation and decreases on reduction. In a reaction, one of the reactants get oxidized and 1 gets reduced, this is known as a redox reaction. The species that oxidizes others and itself gets reduced is known as an oxidizing agent.

Interpretation Introduction

(e)

Interpretation:

The given reaction needs to be classified as oxidation or reduction:

  ${\text{Sn}}^{2+}\left(aq\right)\to {\text{Sn}}^{4+}\left(aq\right)$

Concept Introduction:

In a redox reaction both oxidation and reduction take place simultaneously. Oxidation takes place by loss of electrons and reduction takes place by gain of electrons. The oxidation state of a species increases on oxidation and decreases on reduction. In a reaction, one of the reactants get oxidized and one gets reduced, this is known as a redox reaction. The species that oxidizes others and itself gets reduced is known as an oxidizing agent.
