Does phenolphthalein indicator remain clear in a acid?

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.
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.
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.
How do you make phenolphthalein indicator for titration from powder?
To make phenolphthalein indicator solution from powder, dissolve a small amount of phenolphthalein powder (about 0.1g) in 100mL of ethanol or 95% ethanol and 5% water solution. Stir the mixture until the powder is completely dissolved. This will give you a pink indicator solution suitable for titrations.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
What is the colour of zinc ions mixed with ammonia in phenolphthalein indicator?
The phenolphthalein indicator is pink in basic solutions.

If phenolphthalein is added to HBr?
If phenolphthalein is added to HBr (hydrobromic acid), which is a strong acid, the phenolphthalein indicator will remain colorless because it only changes color in the presence of a base. Since HBr is an acid, it will not cause the indicator to change color.
How do you make phenolphthalein indicator for titration from powder?
To make phenolphthalein indicator solution from powder, dissolve a small amount of phenolphthalein powder (about 0.1g) in 100mL of ethanol or 95% ethanol and 5% water solution. Stir the mixture until the powder is completely dissolved. This will give you a pink indicator solution suitable for titrations.
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.
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.
Does Ammonia turns phenolphthalein in to pink?
No, ammonia does not turn phenolphthalein pink. Phenolphthalein is a pH indicator that turns pink in basic solutions, but ammonia is a weak base and typically does not have a strong enough pH to turn phenolphthalein pink.
Is the universal indicator or phenolphthalein is more accurate?
Universal indicator is generally considered more accurate than phenolphthalein because it provides a broader range of colors to indicate the pH of a solution across a wider pH range. Phenolphthalein is more limited in its pH range and color changes.
