Chapter 9, Problem 9.128E

Interpretation Introduction

Interpretation:

The substances present in the solution being titrated when it has been titrated halfway to the equivalence point have to be stated. The relation of pH of the half-titrated solution to the $\text{p}{K}_a$ for the weak acid is to be stated.

Concept introduction:

pH of a solution is the value of negative logarithm of the concentration of hydrogen ions in a solution. An acidic solution has a pH below $7$, a basic solution has a pH more than $7$ and a neutral solution has a pH equal to $7$. The point in a titration where chemically equivalent quantities of the acid and the base have been mixed together is known as the equivalence point of the titration.
