With a water sample of which the concentration of chloride ion ranges from 1 to 100 mg/l and the volume is above 20 cc, MOHR'S titrimetric method modified by Y. MIYAKE [1] is ordinarily used. Also, with a water sample of which the chloride concentration ranges from 0.1 to 10 mg/l and the volume is above 20 cc, the colorimetric method using mercuric thiocyanate [2] is very convenient.
The method of chloride determination in one drop (ca. 0.02 cc) of a water sample of which the chloride concentration ranges from 10 to 500 mg/l is presented in this report.
