Chapter 11, Problem 11.31P

(a)

Interpretation Introduction

Interpretation:

Volumes at two equivalence points are to be calculated and value of $\text{pH}$ at indicated volumes has to be calculated and a plot of $\text{pH}$ against $V_{\text{a}}$ has to be made.

Concept Introduction:

Dilution formula is given as follows:

  $M_1{V}_1=M_2{V}_2$

Here,

$M_1$ denotes molarity of  acid solution.

$V_1$ denotes volume of acid.

$M_2$ denotes molarity of base.

$V_2$ denotes volume  of base.

(b)

Interpretation Introduction

Interpretation:

Best equivalence point has to be identified.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Appropriate indicator has to be chosen and color change observed has to be given.

Concept Introduction:

Refer to part (a).
