Phenolphthalein is another commonly used indicator for titrations, and is another weak acid. In this case, the weak acid is colourless and its ion is bright pink. Adding extra hydrogen ions shifts the position of equilibrium to the left, and turns the indicatorcolourless.

Phenolphthalein is basic indicator which remain colorless in ... As HCl being a strong acid will neutralize NaOH.

Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions.
Phenolphthalein changes colour sharply at about pH 8. For most purposes, this means that it is pink in alkaline solutions and colourless in acidic solutions.



I hope it helps to you ☺☺

Answer:

Mark me as brainliest answer then I will follow you

Explanation:

Phenolphthalein is an acid indicator,means when we add water (pH 7) to it,it ionises giving a pink colour. ... When we add phenolphthalein to acid due to common ion effect concentration increases. It becomes more than that of concentration. So it appears colourless.
