scope:
This standard describes a method for the potentiometric determination of hydronium ions (H3O+-content of 10 to 500 µ mol/l. Weakly acid and weakly basic components will interfere with the determination. The presence of these interfering components is shown by the deviation between the H3O+-concentrations determined by two successive standard additions. If interfering components are present, the more elaborate method referred to in 11 should be used.
