1 AP Chemistry Lab Brockport High School NY USA Quantitative Determination of Chloride Ion in Solution: Mr Keefer The Mohr Method Introduction The chloride ion (Cl - ) is an important anion found in solids and solutions. Chloride is the predominant anion of sea water with a molarity of approximately 0.54 M. It is an essential component of fluid systems in the body and is part of the regulatory mechanism for body fluid volume and osmotic pressure in cells. An average human excretes approximately 16 mg of chloride per day, thus the detection of the chloride ion becomes germane to water treatment facilities. Bleaching agents can also contribute to chloride ion concentrations in drinking water. The chemical detection of the chloride ion is an important process in water purification and treatment. In this experiment, we will determine the amount of chloride ion in an unknown sample of water using the Mohr method, which relies on the solubility differences of two anions and the titration endpoint of a precipitate. The net ionic reaction during the titration is as
