Chapter 14, Problem 10RQ

Interpretation Introduction

Interpretation: The change in color of indicator from acid color to its base color over a range of $\text{pH}$ values; the condition for change in color of indicator and the authentication of the given statement that the indicator thymol blue contain only single ${\text{-CO}}_{\text{2}}\text{H}$ group and no other acidic or basic functional group is to be stated.

Concept introduction: The acid-base indicators show the color change with change in $\text{pH}$ of the solution.

To determine: The change in color of indicator from acid color to its base color over a range of $\text{pH}$ values; the condition for change in color of indicator and the authentication of the given statement that the indicator thymol blue contain only single ${\text{-CO}}_{\text{2}}\text{H}$ group and no other acidic or basic functional group
