Chapter 13, Problem 101QP

Interpretation Introduction

Interpretation:

The change on titrating an acid of $\text{pH}$ $1.0$ with a base and using bromocresol green as an indicator is to be determined.

Concept Introduction:

Indicators are brightly coloured organic dyes and are weak acids and bases. They give different colours in different $\text{pH}$ ranges of the solution. In titration, the endpoint is determined when the colour of the solution starts to change on adding a base or an acid according to the required titration.
