Determination of chloride in water by Mohr's method

Mohr method of determination of chlorides by titration with silver nitrate is one of the oldest titration methods still in use - it was researched and published by Karl Friedrich Mohr in 1856. The idea behind is very simple - chlorides are titrated with the silver nitrate solution in the presence of chromate anions EXPERIMENT FOURTH: DETERMINATION OF CHLORIDE BY THE MOHR METHOD OBJECTIVES Determine chloride ion concentration in a water sample. BACKGROUND Chloride in the form of chloride (CI) ion is one of the major inorganic anions in water and wastewater, The chloride concentration is higher in wastewater than in raw water because sodium chloride is a common article of diet and passes unchanged through.

Mohr method - argentometric determination of chloride

This method is used when the pH of the solution, after the sample has been prepared, is acidic. If the pH is neutral or basic, Mohr's method or the gravimetric method should be used. The method is illustrated below by using the procedure to determine the concentration of chloride (from sodium chloride) in cheese. Equipment Needed boiling chip Water quality — Determination of chloride — Silver nitrate titration with chromate indicator (Mohr's method) This standard was last reviewed and confirmed in 2021. Therefore this version remains current Mohr method can be used to determine the chloride ion concentration of water samples from many sources such as seawater, stream water, river water and estuary water. Two unknown water sample are tested by using the particular method. The Mohr method works well in a slightly acidic condition, hence the pH of the water sample should be adjusted. method can be considered as reliable, very simple, and particularly suitable for routine analysis of water. Up to the present time three titri-metric procedures for the determination of chloride in water have been recom-mended as standard methods, namely the Mohr and Volhard tit rations with silver nitrate, and a mercurimetric de-termination (2) Mohr method to can't be always applicable in the determination of chlor ide ions concentration from industrial samples, and in consequence other methods must be developed
