Phenolphthalein Solution – 125ml Packs

Phenolphthalein Solution is the most widely recognized pH indicator in chemical education. It is formulated specifically to assist students in understanding acid-base neutralizations, titration curves, and visual endpoint detection in educational science laboratories.

In school chemistry practicals and college laboratories, this solution is predominantly utilized in volumetric titrations involving strong bases and acids, such as sodium hydroxide against hydrochloric acid. Its sharp color change from colorless to pink between pH 8.2 and 10.0 provides students with an unambiguous visual signal for stoichiometric equivalence.

This reliable educational laboratory chemical supports structured curriculum experiments, helping students develop essential laboratory technique and quantitative titrimetric skills. It is an indispensable item for school science prep rooms.

Dropper bottles should be kept tightly capped in an ambient storage cabinet away from open flames. Students should observe routine laboratory safety protocols during all titration sessions.
