"We are … WebAqueous inorganic acids and bases are titrated volumetrically. Since stoichiometry and reaction rate of the Karl Fischer reaction are influenced by the pH, sufficient buffering of the KF solution is a prerequisite for reproducible and accurate results. Optimum conditions are obtained in the neutral pH range (pH 4 - 8).
