Bromothymol blue Yellow 6.0 – 7.6
Thymol blue Yellow 8.0 – 9.6
Phenolphthalein Colorless 8.2 – 10.0

How many type of indicator are there?


Why do we use indicator?

The common use of indicators is to detect the end points of titrations. An indicator’s colour changes when the pH or oxidizing strength of the solution or the concentration of a particular chemical species reaches a critical value.

What are examples of pH indicators?

Acidity and alkalinity are End. to pH so they can also be called pH indicators. Litmus paper, phenolphthalein and red cabbage juice are examples of acid-base indicator.
