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.
What else can I help you with?
Why tartaric assay method falls under alkalimetric direct titration method?
The tartaric assay method falls under the alkalimetric direct titration method because it involves the direct titration of tartaric acid with a standardized alkali solution to determine its concentration. The method is based on the neutralization reaction between the tartaric acid and the alkali, which allows for the quantitative determination of the tartaric acid content present in the sample.
How many number of stereo isomers in tartaric acid?
Tartaric acid has three stereoisomers: meso-tartaric acid and the two enantiomers, D-tartaric acid and L-tartaric acid.
What acid is present in grapes - malic acid tartaric acid acetic acid citric acid?
Tartaric acid is present there. Its also present in grapes. Tartaric acid is present there. Its also present in grapes.
Preparation of pyruvic acid from tartaric acid?
Pyruvic acid can be prepared from tartaric acid through a process called pyrolysis, where tartaric acid is heated under controlled conditions to break down into pyruvic acid and other byproducts. The pyruvic acid can then be isolated and purified from the reaction mixture using various separation techniques.
Does tamarind contains tartaric acid?
Yes, tamarind contains tartaric acid, which contributes to its tangy flavor. Tartaric acid is a natural organic acid found in many fruits, including tamarind.

What is the carboxylic acid in tamarind?
The carboxylic acid in tamarind is tartaric acid. Tartaric acid is a natural organic acid found in many fruits, including tamarind, and it contributes to the sour taste of tamarind.
Why tartaric acid not give phenolphthalein test?
Tartaric acid is a weak acid and does not ionize completely in water to release hydrogen ions. As a result, it does not provide enough free hydrogen ions to turn phenolphthalein indicator pink, which typically requires a pH above 8.2. Tartaric acid's ionization behavior limits its ability to produce the color change associated with the phenolphthalein test.
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.
