Phenolphthalein is commonly used as an indicator in acid-base titrations because it changes color sharply within a specific pH range (approximately 8.2 to 10). In an acid-base titration, the endpoint is reached when the solution becomes either pink (indicating a basic solution) or colorless (indicating an acidic solution), making it easy to detect the completion of the reaction.
What else can I help you with?
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.
In HCl and NaOH titration which indicator is used?
Phenolphthalein is commonly used as an indicator in the titration of hydrochloric acid (HCl) with sodium hydroxide (NaOH). Phenolphthalein changes color from colorless to pink at the endpoint of the titration when all the acid has been neutralized by the base.
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.
Why is phenolphthalein is used in titration experiment?

How much phenolphthalein indicator should be used?
Typically, 1-2 drops of phenolphthalein indicator are sufficient to use in an acid-base titration experiment. It is important not to use too much indicator, as it can affect the accuracy of the titration results.

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.

Which indicator is used in titration for strong acid?
For the titration of a strong acid, the indicator typically used is phenolphthalein. Phenolphthalein changes color in the pH range of 8.2 to 10, which is suitable for titrating a strong acid with a strong base to determine the equivalence point.
Is methylorange the indicator used in the titration of Na2CO3 against HCl solution?
Methyl orange is not commonly used as an indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is a suitable indicator for this titration because it changes color in the pH range of the equivalence point.
Which indicator is used in titration of naoh and h2so4?
Phenolphthalein is commonly used as an indicator in the titration of NaOH and H2SO4. It changes color from colorless to pink as the solution reaches a specific pH range, signaling the endpoint of the titration.
What is the purpose for using phenolphthalein for an acid base titration?
Phenolphthalein is used as an indicator in acid-base titrations because it changes color at a specific pH range. In an acid-base titration, phenolphthalein changes from colorless to pink when the solution reaches a pH around 8.2-10, indicating the endpoint of the titration. This allows for a visual indication of when the reaction is complete.
Why is phenolpthalein used as the indicator for the assay of tartaric acid?
Phenolphthalein is used as an indicator during the titration of tartaric acid because the pH at which phenolphthalein changes color (around pH 8.2-10) is close to the equivalence point of the titration of tartaric acid with a strong base like NaOH. This makes it a suitable indicator for detecting the endpoint of the titration when the acid has been completely neutralized by the base.
