indicator

Meccanismi biochimici e fisiologici

O-cresol phthalein is a reversible pH indicator. The kinetics of the reverse path (red-purple to colorless) is slow, which makes it an appropriate molecule to check the flow pattern in corrugated wall tubes. It is also used for colorimetric determination
