This part of IS0 9963 specifies a method for the titrimetric determination of carbonate alkalinity in natural and drinking water. Using a higher pH value for the endpoint than the method specified in
IS0 9963-1, the influence of other hydrogen acceptors, such as anions of humic acids, is reduced by the procedure. The method is intended for samples with a carbonate alkalinity between 0,01 mmol/l and 4 mmol/l (as H+equivalents). For samples containing higher concentrations of alkalinity, a smaller test portion can be used
for analysis. In this context, carbonate alkalinity is often called total alkalinity and usually has nearly the same numerical
value as methyl orange alkalinity (MO-alkalinity). The endpoint detection, using a pH-meter is less prone to interferences than the use of the indicator.
