Instructions for Use
Analytical MethodMercurimetric Titration: In a slightly acidic solution, chloride ions (Cl-) firmly bond with mercuric ions (Hg2+) to form undissociated mercuric chloride (HgCl2). During the titration of a chloride solution with mercuric ions, Hg2+ ions are
Number of Tests50 – 80
InterferencesStrongly alkaline samples have to neutralised. Bromide and iodide will be titrated as chloride. Chromate, ferric and sulphite ions interfere when present in excess of 10 mg/L.
Measuring RangeThe recommended measuring range is 20 to 200 mg/L (2 – 20 drops @ 10 mg/L) for 5 mL of sample volume. This range can be extended by taking a smaller or larger water sample. For a 2.5 mL sample the measuring range is 40 to 400 mg/L and for a 10 mL sample the range is 10 to 100 mg/L.
Shelf Life2 years
