2.5 mL
The chemicals contained in this test kit may be hazardous if
improperly handled. Read the relevant Health and Safety
Data Sheets before performing the test.
9- Read off the milliliters of titration solution from the
syringe scale and multiply by 100000 to obtain mg/L
(ppm) of Chloride.
Low Range - 500 to 10000 mg/L of Chloride
If the result is lower than 5000 mg/L,
the precision of the test can be improved
by following the steps below.
10- Remove the cap from the large plas-
tic vessel and use the 3 mL plastic
pipette to add 2.5 mL of sample.
11- Follow the instructions from step 4 to 8.
12- Read off the milliliters of titration solution from the syringe
scale and multiply by 10000 to obtain mg/L (ppm) of
Chloride.
Note:
If the sample pH is lower than 2 or higher than 11,
add respectively sodium hydroxide or sulfuric acid to
adjust the pH at a value between 7 and 10.
During titration sample becomes turbid.
Interferences:
Bromide, iodide, cyanide and sulfide; ortho-
phosphate above 250 ppm and polyphosphate above
25 ppm precipitate as silver salts; iron above 10
ppm masks the endpoint. Intensely colored samples
should be adequately treated before performing the
test. Suspended matter in large amounts should be
removed by prior filtration.
