Product Introduction
The titration method phenolphthalein acidity online detector adopts the principle of acid-base titration, which uses acid-base neutralization reaction to determine the acid in the water sample. The mixed solution is continuously stirred to ensure that the reaction proceeds fully. During the titration process, the hydrogen ions in the water sample are gradually neutralized, and the color of the phenolphthalein indicator begins to change from colorless to pink. When the titration endpoint is reached, that is, the hydrogen ions in the water sample are completely neutralized, the color change of the phenolphthalein indicator reaches a stable pink state. The instrument automatically stops titration and records the volume of alkaline solution consumed for calculating the phenolphthalein acidity in the water sample.
