Procedure
Sample solution: To 400 mg of Zinc Acetate in 100 mL of water add 5 mL of ammonia-ammonium chloride buffer and 0.1 mL of eriochrome black.
Analysis: Titrate the Sample solution with 0.05 M edetate disodium until the solution is deep blue in color. Each mL of 0.05 M edetate disodium is equivalent to 10.98 mg of zinc acetate dihydrate (C4H6O4Zn-2H2O).
Acceptance criteria: 98% to 102%
Chloride and Sulfate, Sulfate: A 1.0-g portion shows no more sulfate than corresponds to 0.10 mL of 0.020 N sulfuric acid (0.010%).
Arsenic: NMT 3 ppm
Lead: To pass the test, --- (0.002%).
Alkalies and Alkaline Earths:
Sample solution: Dissolve 2.0 g in 150 mL of water in a 200-mL volumetric flask. Add sufficient ammonium sulfide TS to precipitate the zinc completely and dilute with water to volume. Pass through a dry filter, rejecting the first portion of the filtrate.
Analysis: To 100 mL of the filtrate add 5 drops of sulfuric acid. Evaporate to dryness and ignite.
Acceptance criteria: The weight of the residue does not exceed 2 mg (0.2%).
Insoluble Matter: A 20-g portion, dissolved in 150 mL of water containing 1 mL of glacial acetic acid, shows NMT 1.0 mg of insoluble matter (0.005%).
pH: 6 to 8, in a solution (1 in 20)
Packaging and Storage: Preserve in tight containers.

Procedure
Sample: 350 mg of Zinc Citrate, previously dried at 105C for 2 h
Blank: 60 mL of water
Titrimetric system
Mode: Direct titration
Titrant: 0.05 M edetate disodium
Endpoint detection: Visual
Analysis: Dissolve the Sample in 60 mL of water. Add 10 mL of ammonia-ammonium chloride buffer and 0.1 mL of eriochrome black. Titrate with the Titrant to a blue endpoint. Perform a blank determination.
Calculate the percentage of & zinc (Zn) in the portion of Zinc Citrate taken:
Result = [(V − B) x M x F x 100]/W
V = sample titrant volume (mL)
B = blank titrant volume (mL)
M = titrant molarity (mM/mL)
F = equivalency factor, 65.4 mg/mM
W = sample weight (mg)
Acceptance criteria: NLT 31.3% on the dried basis.
Chloride and Sulfate, Sulfate: A 1.8-g portion shows no more sulfate than corresponds to 0.5 mL of 0.020 N sulfuric acid (NMT 0.05%).
Limit of Arsenic, Cadmium, and Lead: To pass the test.
Arsenic: NMT 3 µg/g
Cadmium: NMT 5 µg/g
Lead: NMT 10 µg/g
Loss on Drying: Dry a sample at 105C for 2 h: it loses NMT 1.0% of its weight.
Microbial Enumeration Tests: The total aerobic microbial count does not exceed 103 cfu/g. The total combined yeasts and molds count does not exceed 102 cfu/g.
Microbiological Procedures for Absence of Specified Microorganisms: It meets the requirements of the test for absence of & Escherichia coli.
