PRO CE DURE
1. Rinse sample tube with sample water. Fill with desired sample size
selected from table above.
2. If sulfites are present, add 5 drops of *Hydrogen Peroxide, 3%
(6091WT). Swirl for 30 seconds.
3. Add *Phenolphthalein Indicator, 0.5% (2258) as follows:
25 mL 2 drops
10 mL 1 drop
5 mL 1 drop
Mix. If solution is pink add *Sulfuric Acid, 0.5N (6090WT), one
drop at a time, swirling after each drop, until pink color changes to
colorless. If solution is colorless, proceed to Step 4.
4. Add *Chloride Reagent A (4069WT) as follows:
25 mL 5 drops
10 mL 2 drops
5 mL 1 drop
Mix. Solution will turn yellow.
5. Add *Silver Nitrate, 0.171N (3824WT), one drop at a time, swirling
and counting the number of drops, until the color turns
orange-brown.
6. Multiply number of drops used in Step 5 as follows:
25 mL multiply by 10
10 mL multiply by 25
5 mL multiply by 50
Record as ppm Chloride.
