Phenolphtalein is an indicator used to find the endpoint of a reaction (specifically an acid-base reaction). It has a pH range of 8.3 to 10.0 which means it can be used for a strong acid to strong base titration or a weak base to strong acid titration. Phenolphthalein is clear when it is in the presence of acid and pink when it is in the presence of a base.

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 methyl orange is used instead of phenolphthalein in hcl and naoh titration?

This is so since the pH at the end point of Phenolphthalein is 9.1 and methyl orange is 3.7. For a strong acid strong base titration which the end point is between 3-11 phenolphthalein is used

Why is a back titration sometimes used for an analysis rather than a direct titration?

Back titrations are used when a reaction occurring in the conical flask can not be detected using an indicator such as phenolphthalein. So, after this titration has been performed, the 'excess' is then titrated with something that can be detected more easily using phenolphthalein etc.
