Testing Process of p-Alkalinity of Water Sample in our lab
P-alkalinity (Phenolphthalein Alkalinity) is a measure of the alkalinity of water due to the presence of hydroxide (OH⁻) ion. It is determined by titrating a water sample with a standard acid using phenolphthalein as the indicator. The endpoint of the titration occurs at pH 8.3, where the pink color of the indicator disappears. Here we […]
