Chapter 15, Problem 15.124CHP

(a)

Interpretation Introduction

Interpretation:

The $\text{pH}$ titration curve for the given titration should be drawn and the equivalence point has to be labelled.

Concept Introduction:

$\text{pH}$titration curve:

$\text{pH}$ titration curve is the plot of $\text{pH}$ of an acid solution versus amount of base added.

(b)

Interpretation Introduction

Interpretation:

The required volume of $\text{0}\text{.010 M}\text{NaOH}$ are to reach the equivalence point should be given.

Concept Introduction:

Acid-base neutralization reaction:

The aqueous solution of acid react with aqueous solution of base to produce soluble salt with water in known as acid-base neutralization reaction.

Equivalence point:

The point, where the amount of base added completely neutralizes the taken amount of acid in the titration is known as equivalence point.

(c)

Interpretation Introduction

Interpretation:

$\text{pH}$ at the equivalence point greater than, equal to or less than 7 has to be given.

Concept Introduction:

Acid-base neutralization reaction:

The aqueous solution of acid react with aqueous solution of base to produce soluble salt with water in known as acid-base neutralization reaction.

Equivalence point:

The point, where the amount of base added completely neutralizes the taken amount of acid in the titration is known as equivalence point.

$\text{pH}$:

The negative log of base 10 ${\text{H}}^{+}$ ion concentration is given by $\text{pH}$ of the solution.

$\text{pH}\text{=}{\text{-log}}_{\text{10}}{\text{[H}}^{\text{+}}\text{]}$

(d)

Interpretation Introduction

Interpretation:

Exact $\text{pH}$ at halfway to the equivalence point should be given.

Concept Introduction:

Acid-base neutralization reaction:

The aqueous solution of acid react with aqueous solution of base to produce soluble salt with water in known as acid-base neutralization reaction.

Equivalence point:

The point, where the amount of base added to completely neutralize the taken amount of acid in the titration is known as equivalence point.

$\text{pH}$:

The negative log of base 10 ${\text{H}}^{+}$ ion concentration is given by $\text{pH}$ of the solution.

$\text{pH}\text{=}{\text{-log}}_{\text{10}}{\text{[H}}^{\text{+}}\text{]}$
