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 shift is needed. The color transition typically occurs in the pH range of 5.0 to 7.0, going from colorless in acidic conditions to yellow in basic solutions. Commonly employed in educational labs for teaching acid-base chemistry, it also finds use in environmental testing and water quality analysis to monitor pH changes in samples. Due to its sensitivity and clear endpoint, it is preferred in certain enzymatic and microbial activity studies where pH stability is critical.
