Used as a pH indicator in laboratory and industrial applications, this solution changes color depending on the acidity or alkalinity of the environment. It is particularly useful in titrations and biochemical assays where a clear visual transition is needed. The color shifts from colorless in acidic conditions (below pH 5.6) to yellow in alkaline solutions (above pH 7.4), making it suitable for detecting moderate pH changes in the range of approximately pH 5.6 to 7.4. Commonly employed in educational labs, environmental testing, quality control processes, and enzyme activity studies where precise pH monitoring is required.
