Is phenolphthalein an indicator?
Yes, phenolphthalein is an indicator commonly used in acid-base titrations to determine the endpoint of the reaction.
Why is phenolphthalein is used in titration experiment?
it is used as an acid-base indicator
What is the equation of sodium hydroxide with phenolphthalein with hydrochloric acid?
The equation for the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) using phenolphthalein indicator is: NaOH + HCl → NaCl + H2O Phenolphthalein is a pH indicator that turns pink in basic solutions and colorless in acidic solutions.
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.
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.
Is phenolphthalein an indicator?
Yes, phenolphthalein is an indicator commonly used in acid-base titrations to determine the endpoint of the reaction.

What is the reaction of hydrochloric acid and phenolphthalein?
Hydrochloric acid (HCl) is a strong acid that will react with phenolphthalein, a pH indicator, causing it to turn colorless in acidic conditions. This reaction occurs due to the change in pH of the solution, which shifts the equilibrium of the phenolphthalein molecule leading to its color change.
What indicator will be used in standardization of sulfuric acid against sodium carbonate?
In standardization of sulfuric acid against sodium carbonate, the indicator typically used is phenolphthalein. Phenolphthalein turns pink in basic solutions, which helps in determining the endpoint of the reaction between sulfuric acid and sodium carbonate.
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!!
Is phenolphthalein the indicator used in the titration of Na2CO3 against HCl solution?
Type your answer here... Phenolphthaelin indicator changes its colour at 8.3 pH. But the end point of this reaction is at pH 7. In weak base Strong acid case the curve gives sharp change from 3.2 to 6.0 pH. Hence phenolphthalein indicator will not be advicable.
The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
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.
Why you are adding phenolphthalein as a indicator?
One would add phenolphthalein as an indicator for bases with a pH of 8.2 to 10.0 If the phenolphthalein changes color from colorless to pink or red, a base with a pH between the aforementioned pH values is present.
