PHENOLPHTHALEIN (White) (pH 8.2-9.8)

Phenolphthalein White is a white crystalline powder commonly used as an indicator in?the acid-base titrations in analytical chemistry laboratories. It is particularly useful in titrations where precise determination of endpoint is necessary for accurate experimental results. The compound is a weak acid and can liberate H? ions in solution. During acid-base titrations, Phenolphthalein helps visually detect the point at which a solution becomes alkaline by producing a distinct color change. This characteristic results in its widespread use as an indicator in both quantitative chemical analysis and educational laboratory experiments. Phenolphthalein White is insoluble in water but easily soluble in alcohol, which is useful for the preparation of indicator solutions in the laboratory. Its reliable pH-sensitive response and well-established analytical characteristics make it appropriate for the routine titration work, research applications, and general chemical testing procedures.

Classic acid-base indicator for titration and analytical chemistry applications.
