0.1% alcoholic methyl red solution is a pH indicator commonly used in acid-base titrations and various chemical reactions requiring clear visual pH transition. It is prepared by dissolving methyl red in ethanol to obtain a 0.1% (w/v) concentration.
🧪 Applications
Titrations: Methyl red is frequently used in acid-base titrations. The solution changes color sharply over a specific pH range (approximately pH 4.4 to 6.2), helping determine the endpoint of the titration.
Non-aqueous systems: Because the indicator is dissolved in ethanol, it can be used in organic or non-aqueous environments where water is not suitable.
