Chapter 16, Problem 9SAQ

Interpretation Introduction

Interpretation:

The option corresponding to the correct value of $\text{pH}$ for the titration between $20.0\text{mL}$ of $\text{0}\text{.150}\text{M}$ ethylamine and $0.0981\text{M}$$\text{HCl}$ after the addition of $\text{5}\text{.0}\text{mL}$ of $\text{HCl}$ is to be identified.

Concept introduction: The titration between an acid and a base is used to determine the concentration of an acid or base by neutralizing the acid of unknown concentration with a base of known concentration or vice-versa.

To determine: The option corresponding to the correct value of $\text{pH}$ for the titration between $20.0\text{mL}$ of $\text{0}\text{.150}\text{M}$ ethylamine and $0.0981\text{M}$$\text{HCl}$ after the addition of $\text{5}\text{.0}\text{mL}$ of $\text{HCl}$ .

Correct answer:

The option (d) is correct.
