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.
What is the purpose of phenolpthalein?
Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.
What is phenolphthalein made of?
Phenolphthalein is made up of, H20, C14, O4,
What is phenolphthalein?
it is a agar medium for Microbiology containing phenolphthalein biphosphate. It is used in Petri plates and detects the phosphatase character of microbial colonies but requires final addition of alkali to color the phenolphatlein and the color rapidly fades.
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 colour of zinc ions mixed with ammonia in phenolphthalein indicator?

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.
What is the use of phenapthalein?

Is methyl orange the indicator used in the titration of na2co3 against hcl solution?
No, methyl orange is not commonly used as the indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is the indicator of choice for this titration, as the endpoint is at a pH of around 8.2, which is the color change range of phenolphthalein.
