One would add phenolphthalein as an indicator for bases with a pH of 8.2 to 10.0
If the phenolphthalein changes color from colorless to pink or red, a base with a pH between the aforementioned pH values is present.

An indicator is not necessary; but if you want phenolphthalein is colorless at pH=7.
What is the action of sodium hydroxide on the colour of phenolphthalein?
Phenolphthalein is pink in basic solutions.Phenolphthalein is used as an indicator in volumetry - acid-base titration.
What is the purpose of phenolpthalein?
Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.
What is pherolpthalein indicator?

Is the universal indicator or phenolphthalein is more accurate?
THe universal indicator is more accurate as it can detect different ranges in the pH, whereas phenolphthalein only changes at a ph of 8.0
What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is the indicator to see if it is more acidic or more basic
Why you use phenolphthalein in titration?

Why phenolphthalein used in titration?
it acts as acid base indicator
Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?
Sodium hydroxide is a base. And phenolphthalein is a pH indicator that changes color at around a pH of 8.4, so you can tell when your solution that endpoint.
How much phenolphthalein indicator should be used?
A few drops of any indicator is generally enough to get a reading.
What indicator is used in the preparation of sodium chloride?
An indicator is not necessary; but if you want phenolphthalein is colorless at pH=7.
Is sodium hydroxide a base or acid how will you justify?
Adding an acid base indicator to a sodium hydroxide solution can verify that it is an alkaline solution. For example, phenolphthalein turns pink in an NaOH solution.
