- Identification
- A- When strongly heated, it assumes a yellow color that disappears on cooling
- B-In the presence of sodium acetate, solutions of zinc salts yield a white precipitate with hydrogen sulfide. This precipitate is insoluble in acetic acid, but is dissolved by 3 N hydrochloric acid.
- Iron and heavy metals
- White precipitates are formed when potassium ferrocyanide TS is added to the first portion and when sodium sulfide TS is added to the second portion.

Technical Details & Test Data
- Alkalinity
- if a red color is produced, not more than 0.30 mL of 0.10 N hydrochloric acid is required to discharge it.
- Carbonate and color solution
- no effervescence occurs and the resulting solution is clear and colorless
- Lead
- The addition of 5 drops of potassium chromate TS produces no turbidity or precipitate
