Phenolphthalein Solution Extra Pure
SHORT DESCRIPTION
Phenolphthalein Solution Extra Pure is a laboratory-grade pH indicator solution, commonly used in titration procedures to determine the endpoint of acid-base reactions. It is prepared by dissolving phenolphthalein powder in an appropriate solvent, typically ethanol or water-alcohol mixtures, resulting in a clear, colorless solution that turns vivid pink in basic conditions—usually in the pH range of 8.2 to 10.0.
This high-purity solution offers excellent sensitivity and reliability for analytical chemistry, quality control, and educational demonstrations. It is especially favored in alkalinity testing, neutralization reactions, and various standard laboratory protocols. Proper handling is essential, including the use of gloves and eye protection, as the solution may cause skin or eye irritation upon contact. Store tightly sealed, away from direct light and incompatible substances like strong acids or oxidizers, to maintain its stability and effectiveness.
