Chapter 16.4, Problem 11PE

Interpretation Introduction

Interpretation: The validation of the fact that the midpoint $\text{pH}$ in the first stage of an alkalinity titration is always the same as $\text{p}{K}_{\text{a}}$ of carbonic acid is to be stated.

Concept introduction: Titration is defined as the process in which the addition of one solution of known concentration to a known volume of unknown concentration takes place till the reaction reaches neutralization.

To determine: If the midpoint $\text{pH}$ in the first stage of an alkalinity titration is always the same as $\text{p}{K}_{\text{a}}$ of carbonic acid.
