Question

what will happen if we add phenolphthalein to NH4OH

Answer 1

Answer:

As Amonium Hydroxide is a base so phenolphthalein will turn pink.

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.
