Determination of chloride in water by mohr method
Mohr method is one of the significant methods for determination of chloride in water. It is also known as Argentometric method. Chloride ion is a negatively charged ion. This method is appropriate for neutral or slightly alkaline water. Water sample is titrating against standard AgNO 3 solution by using potassium chromate indicator. It is a ...
Standard Test Methods for Chloride Ion In Water - ASTM …
2010年12月31日 · Chloride ion is under regulation in water, and must, therefore, be measured accurately. It is highly detrimental to high-pressure boiler systems and to stainless steel, so monitoring is essential for prevention of damage. Chloride analysis is widely used as a tool for estimating the cycles of concentration, such as in cooling tower applications.
Test for Chloride (Cl-) Ion
In Qualitative analysis for chloride ion, colors, solubility, precipitates of chloride compounds are important and we are learn different experiments to test the presence of chloride ion. First, we discuss which experiments can be conducted to test for chloride ion and then discuss how they are used to identify chloride ion from other anions.

Determination of Chloride in Water - Biocyclopedia
To determine the amount of chloride (in the form of Cl –) present in the given water sample by Mohr’s method. If water containing chlorides is titrated with silver nitrate solution, chlorides are precipitated as white silver chloride. Potassium chromate is used as …
This 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. Seawater is used as the example here. The pH of the sample solutions should be between 6.5 and 10. (Refer to the additional notes (3) for the explanation).
Test for the Presence of Chloride in Water. This SOP describes how to test water for the presence of chloride ion at the 0.5 mg/L level by the Current USP for Sterile Purified Water. 3.1 The Process Analytics (PA)Technical Operations Lead has the authority to define this procedure.
Testing Chloride in Water - YouTube
Learn how to test chloride levels in water with our step-by-step guide. This video will walk you through the process, from gathering materials to recording r...
Determination of Chloride in Water by Automatic Titration Introduction Chloride in water is determined using the preprogrammed method, Chloride Water. Chloride in the sample is titrated to the equivalence point by argentometric titration using a silver nitrate titrant.1,2,3 A silver billet electrode is used to follow the titration.
To determine the concentration of chloride, first pipet 10ml of filtered water sample into a 250ml Erlenmeyer flask and dilute by adding 65ml of distilled water. Test the pH of the diluted water sample with pH test paper. If the pH is not between a pH of 6 and 8, then use nitric acid or sodium hydroxide to bring the pH to an appropriate level.
