产品介绍

The titration method uses the acid-base titration method, which uses acid-base neutralization to determine the acid in the water sample, continuously stirring and mixing the solution to ensure the reaction proceeds fully. During titration, the hydrogen ions in the water sample are gradually neutralized, and the color of the phenolphthalein indicator changes from colorless to pink. When the titration endpoint is reached, the hydrogen ions in the water sample are completely neutralized, and the color change of the phenolphthalein indicator reaches a stable pink state. The instrument automatically stops titration, recording the volume of consumed alkali solution to calculate the phenolphthalocyanin acidity in the water sample.
