Water quality — Determination of chloride — Silver nitrate titration with chromate indicator (Mohr’s method)


This International Standard specifies a titration
method for the determination of dissolved chloride
in water. The method is applicable to the direct determination
of dissolved chloride in concentrations
between 5 mg/l and 150 mg/l. The working range
may be extended to 400 mg/l by using a burette of
larger capacity or by sample dilution. Due to many
interferences the method is not applicable to heavily
polluted waters of low chloride content.
