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.
Is phenolphthalein an indicator?
Yes, phenolphthalein is an indicator commonly used in acid-base titrations to determine the endpoint of the reaction.
What is chemical which mixed with caustic soda becomes pink?
Phenolphthalein is the indicator that turns pink in alkaline solutions it WILL NOT show any colour in an acid environment!!
Why is phenolphthalein is used in titration experiment?
it is used as an acid-base indicator
Whats the hazard sign of Phenolphthalein indicator?
Phenolphthalein is not classified as a hazardous chemical and therefore does not have a specific hazard sign associated with it. It is commonly used as an acid-base indicator in laboratories and is considered to be relatively safe to handle.
What is phenolphthalein indicator used for in chemical experiments?

What chemical change in orange?
You think probable to phenolphthalein used as a pH indicator.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.

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.
Why is phenolphthalein is used in titration experiment?
it is used as an acid-base indicator
Whats the hazard sign of Phenolphthalein indicator?
Phenolphthalein is not classified as a hazardous chemical and therefore does not have a specific hazard sign associated with it. It is commonly used as an acid-base indicator in laboratories and is considered to be relatively safe to handle.
What can you use in place of bromophenol blue?
Methyl orange or phenolphthalein can be used as alternatives to bromophenol blue in certain experiments requiring a pH indicator. It is important to consider the specific requirements of the experiment and the pH range of the indicator being used.
Why is phenolphthalein used in the titration experiment?
Phenolphthalein is used in titration experiments as an acid-base indicator because it changes color at a specific pH range (pH 8.2-10.0), making it easy to visually detect the endpoint of the titration when the solution changes from acidic to basic or vice versa. This helps in determining the volume of titrant needed to reach the equivalence point accurately.
Is phenolphthalein dangerous?
Phenolphthalein is considered safe for use in laboratory experiments and as a pH indicator in small quantities. However, it is no longer used in medications due to its potential carcinogenic properties. Prolonged exposure or ingestion of large amounts of phenolphthalein can be harmful and should be avoided.
