Precipitation Titration: Determination of Chloride by the ...
academic.brooklyn.cuny.eduIn this experiment, the amount of chloride in an unknown sample was determined by Mohr titration. The titration was carried out at a pH between 7 and 10 because chromate ion is the conjugate base of the weak chromic acid (2, 3). Therefore, when the pH is lower than 7, chromate ion is protonated and the chromic acid form predominates in the ...

Chlorides in Fresh Water
cels.uri.educhloride levels as one indicator of pollution in a body of water. Natural Chlorides Chlorides constitute approximately 0.05% of the earth’s crust. Chloride concentrations of between 1 and 100 ppm (parts per million) are normal in freshwater. Chloride ions come into solution in water in underground aquifers, geological formations that
