General

What is Phenolphthalein 1% Alcoholic Indicator Solution? It is a chemical solution used primarily as a pH indicator in titrations. It contains 1% phenolphthalein dissolved in alcohol (ethanol or methanol), making it a highly effective and widely used indicator.

Frequent Uses

Acid-Base Titrations: Used as a pH indicator, phenolphthalein is colorless in acidic solutions and turns pink in basic solutions, facilitating the detection of the endpoint in titrations.

Carbonation Testing in Concrete: Applied to concrete surfaces to assess carbonation; a color change to pink indicates uncarbonated, alkaline concrete, while no color change suggests carbonation has occurred.

Educational Demonstrations: Utilised in chemistry education to visually demonstrate pH changes and the principles of acid-base reactions.
