Chapter 17, Problem 17.93SP

Interpretation Introduction

(a)

Interpretation:

The pH at the equivalence point for the titration of $0.10\text{ M}$ solutions of ${\text{HNO}}_{\text{2}}\text{ and NaOH}$ and suitable indicators for the titration should be determined.

Concept introduction:

The equivalence point is the point at which the moles of the titrant added is completely neutralized the analyte solution or the point at which the moles of acid equivalent to the moles of base. Indicators are the substances that change the color according to the pH of the mixture and help to visually identify the equivalence point which is called the endpoint.

Interpretation Introduction

(b)

Interpretation:

The pH at the equivalence point for the titration of $0.10\text{ M}$ solutions of $\text{HI}$ and $\text{NaOH}$ suitable indicators for the titration should be determined.

Concept introduction:

The equivalence point is the point at which the moles of the titrant added is completely neutralized the analyte solution or the point at which the moles of acid equivalent to the moles of base. Indicators are the substances that change the color according to the pH of the mixture and help to visually identify the equivalence point which is called the endpoint.

Interpretation Introduction

(c)

Interpretation:

The pH at the equivalence point for the titration of $0.10\text{ M}$ solutions of ${\text{CH}}_{\text{3}}{\text{NH}}_{\text{2}}$ and $\text{HCl }$ suitable indicators for the titration.

Concept introduction:

The equivalence point is the point at which the moles of the titrant added is completely neutralized the analyte solution or the point at which the moles of acid equivalent to the moles of base. Indicators are the substances that change the color according to the pH of the mixture and help to visually identify the equivalence point which is called the endpoint.
