Chapter 5, Problem 100SAE

Interpretation Introduction

(a)

Interpretation:

The half equation method of balancing redox equation needs to be explained.

Concept introduction:

A redox reaction is the reaction in which one reactant gets oxidized and another reactant gets reduced.

On losing electron/s by reactant, it gets positively charged/negative charge decreases and undergoes oxidation. On the other hand, when a reactant gain electron/s, it undergoes reduction and gets negatively charged/positive charge decreases on it.

Interpretation Introduction

(b)

Interpretation:

Disproportionation reaction needs to be explained.

Concept introduction:

A redox reaction is the reaction consists of reactant in which one reactant gets oxidized and another reactant gets reduced.

On losing electron/s by reactant, it gets positively charged/negative charge decreases and undergoes oxidation. On the other hand, when a reactant gain electron/s, it undergoes reduction and gets negatively charged/positive charge decreases on it.

Interpretation Introduction

(c)

Interpretation:

The term titration needs to be explained.

Concept introduction:

A titration is the method in which a known solution which termed as titrant is added from a burette to a measured amount of unknown solution and titrated to complete the reaction.

The unknown solution usually kept in conical or titration flask. A solution with known concentration is required for the determination of unknown solution with its concentration.

Completion of the reaction indicated by change in color of solution.

Interpretation Introduction

(d)

Interpretation:

The standardization of a solution needs to be explained.

Concept introduction:

A titration is the method in which a known solution which termed as titrant is added from a burette to a measured amount of unknown solution and titrated to complete the reaction.

The unknown solution usually kept in conical or titration flask. A solution with known concentration is required for the determination of unknown solution with its concentration.

Completion of the reaction indicated by change in color of solution.
