Chapter 15.4, Problem 15.12P

(a)

Interpretation Introduction

Interpretation:

The $\text{pH}$ serine should be calculated at $\text{66\%}$ dissociation.

Concept Introduction:

Henderson–Hassel Balch Equation:

The $\text{pH}$ of the buffer solution is given by Henderson–Hassel Balch Equation and it is,

$\text{pH}{\text{=pK}}_{\text{a}}\text{+}\text{log}\frac{\text{[base]}}{\text{[acid]}}$

(b)

Interpretation Introduction

Interpretation:

The $\text{pH}$ serine should be calculated at $\text{5\%}$ dissociation.

Concept Introduction:

Henderson–Hassel Balch Equation:

The $\text{pH}$ of the buffer solution is given by Henderson–Hassel Balch Equation and it is,

$\text{pH}{\text{=pK}}_{\text{a}}\text{+}\text{log}\frac{\text{[base]}}{\text{[acid]}}$
