Zinc Carbonate & Basic Zinc Carbonate Specifications of Commercial Pure & USP Grade Manufacturers & Exporters Please check Zinc Carbonate & Basic Zinc Carbonate USP NF ACS BP Ph Eur EP JP IP Analytical reagent FCC Food grade Manufacturers our associates world class FDA-GMP approved, ISO-9001 Certified facility Anmol Chemicals Basic Zinc Carbonate CAS Number 5263-02-5 Zinc Carbonate CAS Number 3486-35-9 Zinc Carbonate USP Grade Specifications: 3Zn(OH)2-2ZnCO3 --- 548.96 Basic zinc carbonate; Zinc subcarbonate CAS 5263-02-5 DEFINITION Zinc Carbonate contains the equivalent of NLT 70.0% of zinc oxide (ZnO). This 70% ZnO is equivalent to 56.1% Zinc content. We can also offer Zinc Carbonate of minimum 60% Zinc content. IDENTIFICATION A. Identification Tests—General, Zinc. ASSAY Procedure Analysis: Transfer 2.0 g to a 125-mL conical flask, add 50.0 mL of 1 N sulfuric acid and swirl to dissolve. Add 3 drops of methyl orange and titrate with 1 N sodium hydroxide to a yellow endpoint. Each mL of 1 N sulfuric acid is equivalent to 40.69 mg of zinc oxide (ZnO). Acceptance criteria: NLT 70.0% Chloride and Sulfate Chloride: Sample solution: Dissolve 1.0 g in a mixture of 20 mL of water and 3 mL of nitric acid. Acceptance criteria: The Sample solution shows no more chloride than corresponds to 0.03 mL of 0.02 N hydrochloric acid (0.002%). Sulfate: Sample solution: Dissolve 10.0 g in a mixture of 75 mL of water and 10 mL of hydrochloric acid, and filter. Neutralize the filtrate with ammonium hydroxide and dilute with water to 100 mL. Analysis: To 10.0 mL of the Sample solution add 1 mL of 0.6 N hydrochloric acid and 1 mL of barium chloride and allow to stand for 10 min. Acceptance criteria: The Sample solution shows no more turbidity than that produced in a solution containing 0.10 mL of 0.02 N sulfuric acid and the same quantities of reagents used to prepare the Sample solution (0.01%). Iron: NMT 0.002% Lead: NMT 5 ppm Insoluble Matter: Sample solution: Dissolve 10 g in a mixture of 100 mL of water and 7 mL of sulfuric acid. Analysis: Heat the Sample solution on a steam bath for 1 h. Filter the solution through a tared sintered-glass crucible, wash with hot water, and dry the crucible at 105C. Cool, and weigh. Acceptance criteria: The residue weighs NMT 2 mg (0.02%). Substances Not Precipitated by Ammonium Sulfide: Sample solution: Dissolve 1.0 g in 10 mL of water and 2 mL of sulfuric acid. Dilute with water to 80 mL, add 10 mL of ammonium hydroxide, and pass hydrogen sulfide through the solution for 30 min. Dilute with water to 100 mL, and allow the precipitate to settle. Decant the supernatant through a filter. Use the clear filtrate. Analysis: Transfer 50 mL of the Sample solution to a tared dish and evaporate to dryness. Ignite, gently at first, and finally at 800±25C. Cool, and weigh. Acceptance criteria: The weight of the residue is NMT 2 mg (0.4%). Packaging and Storage: Preserve in tight containers.
