Product Description:
Widely used as a pH indicator in acid-base titrations, this solution is particularly effective in detecting the endpoint in strong acid-strong base reactions. It remains colorless in acidic and neutral solutions and turns a distinct pink to red in basic conditions, typically above pH 8.2. Commonly used in educational laboratories for titration experiments due to its sharp color change and ease of observation. Also employed in some industrial processes to monitor alkalinity. Historically used in laxatives, but this application has been discontinued in many regions due to health concerns.
