Chloride Test Kits
Manufacturer: Chemetrics, Inc.
Chloride is the most common inorganic anion found in water and wastewater. A limit of 250 mg/L Cl has been placed on drinking water supplies, as this is the level at which water begins to taste salty when sodium is the cation. Natural sources of salt are the ocean and various salt deposits above and below ground. Chloride is very corrosive to most metals in systems with elevated pressures and temperatures such as boilers and oil-drilling equipment. The Silver Nitrate Method: In the Argentometric method, potassium chromate is used to indicate the end point of the silver nitrate titration of chloride. Red silver chromate is precipitated before silver chloride is formed. The Mercuric Nitrate Method: CHEMetrics employs a mercuric nitrate titrant in acid solution with diphenylcarbazone as the end point indicator. Results are expressed as ppm (mg/L) Cl. The Ferric Thiocyanate Method: The Chloride Vacu-vials® test employs the ferric thiocyanate chemistry. Chloride reacts with mercuric thiocyanate to liberate thiocyanate ion. Ferric ion reacts with thiocyanate ion to produce an orange-brown thiocyanate complex in proportion to the chloride concentration. Results are expressed as ppm (mg/L) Cl.
