Product Description:
Widely used as a pH indicator in acid-base titrations, this solution is colorless in acidic and neutral environments and turns bright pink to purple in basic conditions, typically above pH 8.2. It is commonly employed in laboratory settings for educational demonstrations and analytical chemistry to determine the endpoint of titrations involving strong acids and strong or weak bases. Due to its sharp color change, it provides a clear visual signal when the solution becomes alkaline. It is also used in some industrial processes to test for alkalinity and in water testing. However, due to its potential health hazards, its use has been limited in certain applications, especially those involving ingestion or long-term exposure.
