Why is thymol blue used as the indicator for titration of acetic acid and naoh?
An indicator that changes its colour around pH value 5 should be used in this titration. Alternatively, instead of Thymol Blue, Methyl Orange or Methyl Red may be used.
In HCl and NaOH titration which indicator is used?
Phenolphthalein indicates red for acids and blue for bases.
Why is phenolphthalein used in the titration experiment?
it is used as an acid-base indicator
What volume of NaOH was used in the titration?

What is meant by External Indicator used in titration?
Indicators used outside the titration flask are termed as external indicators. A very commonly used external indicator is potassium ferricyanide

The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
