Why is phenolphthalein used in the titration experiment?
it is used as an acid-base indicator
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.

What is difference between external and internal indicators used in titration?
Internal indicators that are used in titration exist in the titration reaction as either a reactant or a product. External indicators is added to the reaction mixture, but does not exist in the reaction.
Is phenolpthalen an indicator?
Yes - it's used in acid-base titration.
What are different types of indicator used in titration?
phenolphthalein is one i know.
Why is an indicator not used in a redox titration?
Because the endpoints are easily observed.
Why is phenolphthalein indicator used in the titration of oxalic acid against sodium hydroxide?
Yes. Phenolphthalein can be used as an indicator for the titration of a weak acid (oxalic acid) against strong base (sodium hydroxide).
Why in titration of kmno4 no indicator is used?
Because KMnO4 is an internal indicator.. No need to have any indicator.. it has distinctly different colour when it is reduced
Which indicator is used for the titration of weak acid and strong base?
Phenopthalene is used commonly
