Is phenolphthalein an indicator?
Yes, phenolphthalein is an indicator commonly used in acid-base titrations to determine the endpoint of the reaction.
What is phenolphthalein indicator used for in chemical experiments?
Phenolphthalein indicator is used in chemical experiments to determine the acidity or alkalinity of a solution by changing color based on the pH level.
What is the most appropriate indicator for the strong acid/strong base titration?
The most appropriate indicator for a strong acid/strong base titration is phenolphthalein.
Why is phenolphthalein used as an indicator in chemical experiments?
Phenolphthalein is used as an indicator in chemical experiments because it changes color depending on the acidity or alkalinity of a solution. This makes it easy to visually determine the endpoint of a reaction or the pH level of a solution.
Does phenolphthalein indicator remain clear in a acid?

What is the colour of zinc ions mixed with ammonia in phenolphthalein indicator?
The phenolphthalein indicator is pink in basic solutions.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
Why is phenolphthalein used as an indicator in chemical experiments?

Which indicator is used in titration for strong acid?
For the titration of a strong acid, the indicator typically used is phenolphthalein. Phenolphthalein changes color in the pH range of 8.2 to 10, which is suitable for titrating a strong acid with a strong base to determine the equivalence point.
What is the indicator in titration reactions that turns pink in basic solutions?
Phenolphthalein is the indicator that turns pink in basic solutions during titration reactions.
Why use phenolphthalein in ester hydrolysis?
Phenolphthalein is used in ester hydrolysis reactions as an acid-base indicator. It changes color at the endpoint of the reaction, helping to determine when the reaction is complete. In ester hydrolysis, phenolphthalein turns from colorless to pink as the solution goes from acidic to slightly basic.
How do you determine if a substance is an acid or a base using phenolphtalein indicator?
Phenolphthalein is colorless in acidic solutions and pink in basic solutions. By adding phenolphthalein to a substance, you can observe the color change to determine if the substance is acidic or basic based on the change in color.
What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is a pH indicator that turns pink in basic solutions. When added to sodium hydroxide, which is a strong base, the phenolphthalein will turn pink to indicate that the solution is basic.
