Chloride Test Kit, titrimetric

For U.S. Customers: Contains mercury; Do not place in trash - dispose according to local, state, or federal laws.

Chloride is found in the earth´s crust and can therefore also be found in all natural waters at some concentration. This basic parameter of water analysis can be checked using our Chloride Test. This MQuant^® Chloride test (formally MColortest^®) is suitable for the titrimetric determination using a graduated syringe.

Method
In nitric solution chloride ions are titrated with mercury(II) nitrate solution against 1,5-diphenylcarbazone as the indicator, forming slightly dissociated mercury(II) chloride in the process. At the titration end-point, excess mercury(II) ions react with the indicator to form a blue-violet complex. The chloride concentration is determined from the consumption of titration solution (mercurimetric determination).

The test can be used in

• Groundwater, surface water, and seawater (after dilution)
• Waters from aquaculture
• Drinking water and mineral water
• Water for concrete in the construction industry
• Industrial water and wastewater
• Boiler and boiler feed water, cooling water
• Swimming-pool water
• Food after appropriate sample pretreatment
• Soils and fertilizers after appropriate sample pretreatment

Method: titrimetric with titration pipette MQuant^®
