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.
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.
What is the purpose of adding phenolphthalein during titration?
Phenolphthalein is added as an indicator during titration to visually indicate the endpoint of the reaction. It changes color at a specific pH, usually from colorless to pink, which helps the titrator determine when the reaction is complete and the equivalence point has been reached.
What colour in sulfuric acid is phenolphthalein?
Phenolphthalein is colorless in sulfuric acid.
Which Colour do alkali turn phenolphthalein?
Alkalis turn phenolphthalein pink or magenta.
What is an example of indicate?
phenolphthalein, methyl orange.
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.
Can phenolpthalein solution be used to prove that toothpaste is a base?
Phenolphthalein changes from colorless to pink in the range of pH 8.2 - 10. If toothpaste has a pH that is below this range, phenolphthalein will not indicate the basicity. if the pH is higher, which I believe it is in most (some) toothpastes, then phenolphthalein can be used, because it will turn from colorless to pink.
Is the universal indicator or phenolphthalein is more accurate?

What colour in sulfuric acid is phenolphthalein?
Phenolphthalein is colorless in sulfuric acid.
Is phenolphthalein a compound?
Yes, phenolphthalein is a compound with the molecular formula C20H14O4.
Which Colour do alkali turn phenolphthalein?
Alkalis turn phenolphthalein pink or magenta.
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.
What color does NaoH turn when phenolphthalein?
NaOH turns pink when phenolphthalein is added.
What is the color change of phenolphthalein in a basic solution?
Phenolphthalein turns pink in a basic solution.
What is th function of phenolphthalein in titration?
Phenolphthalein is used as a pH indicator in acid-base titrations. It changes color in response to changes in pH, turning from colorless in acidic solutions to pink in basic solutions. This color change helps in determining the endpoint of the titration when the reaction is complete.
