Beschreibung:
Phenolphthalein disodium salt is a pH indicator that changes color at a certain pH level. It is used to monitor the pH of liquids and soil. The color change can be detected by eye or with the use of instruments, such as sensors or cavity probes. Phenolphthalein is often used in conjunction with other indicators to make it easier to read the results. Phenolphthalein is also used as an acid-base indicator in titrations, monitoring the equivalence point between acid and base solutions.
