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 effective in titrations and pH monitoring where a clear visual change is needed. The color shifts from colorless in acidic conditions to yellow in basic solutions, typically around pH 5.6 to 7.6, making it useful for detecting slight pH changes in aqueous systems. Commonly applied in educational experiments, environmental testing, and quality control processes where precise pH tracking is required.
