Zinc Carbonate USP
3Zn(OH)2·2ZnCO3 549.01
Basic zinc carbonate.
Zinc subcarbonate [CAS 3486-35-9]
Zinc Carbonate contains the equivalent of not less than 70.0 percent of ZnO.

Packaging and storage: Preserve in tight containers.
Identification: A solution of it in a slight excess of hydrochloric acid responds to the tests for Zinc.
Insoluble matter: Dissolve 10-g Zinc Carbonate in a mixture of 100 mL of water and 7 mL of sulfuric acid, and heat on a steam bath for 1 hour. Filter the solution through a tarred sintered-glass crucible, wash with hot water, dry the crucible at 105 , cool, and weigh: the residue weighs not more than 20 mg (0.02%).
ChlorideL A 1.0-g Zinc Carbonate dissolved in a mixture of 20 mL of water and 3 mL of nitric acid shows no more chloride than corresponds to 0.03 mL of 0.02 N hydrochloric acid (0.002%).
Sulfate: Dissolve 10.0-g Zinc Carbonate in a mixture of 75 mL of water and 10 mL of hydrochloric acid, and filter. Neutralize the filtrate with ammonium hydroxide, dilute with water to 100 mL, and mix. To 10.0 mL of this solution add 1 mL of 0.6 N hydrochloric acid and 1 mL of barium chloride TS, mix, and allow to stand for 10 minutes. This test solution shows no more turbidity, if any, 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 test solution (0.01%).
Iron: Dissolve 1.0-g Zinc Carbonate in 20 mL of water and 3 mL of hydrochloric acid: the limit is 0.002%.
Lead: the limit is 5 ppm.
Substances not precipitated by ammonium sulfide: Dissolve 1.0-g Zinc Carbonate 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 about 30 minutes. Dilute with water to 100 mL, and allow the precipitate to settle. Decant the supernatant through a filter, and transfer 50 mL of the clear filtrate to a tarred dish, evaporate to dryness, ignite, gently at first and finally at 800 ± 25 , cool, and weigh: the weight of the residue does not exceed 2 mg (0.4%).
Assay: Transfer about 2.0 g of Zinc Carbonate, accurately weighed, to a 125-mL conical flask, add 50.0 mL of 1 N sulfuric acid VS, and swirl to dissolve. Add 3 drops of methyl orange TS, and titrate with 1 N sodium hydroxide VS to a yellow endpoint. Each mL of 1 N sulfuric acid consumed is equivalent to 40.69 mg of ZnO.

Zinc Oxide BP Grade
Ph Eur
ZnO -- 81.4 -- CAS 1341-13-2

DEFINITION
Content: 99.0 per cent to 100.5 per cent (ignited substance).

CHARACTERS
Appearance: Soft, white or faintly yellowish-white, amorphous powder, free from gritty particles.
Solubility: Practically insoluble in water and in ethanol (96 per cent). It dissolves in dilute mineral acids.

IDENTIFICATION
A. It becomes yellow when strongly heated; the yellow colour disappears on cooling.
B. Dissolve 0.1 g in 1.5 ml of dilute hydrochloric acid and dilute to 5 ml with water. The solution gives the reaction of zinc.

TESTS
Alkalinity: Shake 1.0 g with 10 ml of boiling water. Add 0.1 ml of phenolphthalein solution and filter. If the filtrate is red, not more than 0.3 ml of 0.1 M hydrochloric acid is required to change the colour of the indicator.
Carbonates and substances insoluble in acids: Dissolve 1.0 g in 15 ml of dilute hydrochloric acid. It dissolves without effervescence and the solution is not more opalescent than reference suspension and is colourless.
Arsenic: Maximum 5 ppm, determined on 0.2 g.
Cadmium: Maximum 10.0 ppm.
Iron: Maximum 200 ppm.
Lead: Maximum 50.0 ppm.
Loss on ignition: Maximum 1.0 per cent, determined on 1.00 g by ignition to constant mass at 500 ± 50C.

ASSAY: Dissolve 0.150 g in 10 ml of dilute acetic acid R. Carry out the complexometric titration of zinc. 1 ml of 0.1 M sodium edetate is equivalent to 8.14 mg of ZnO.

Function: Nutrient.

REQUIREMENTS
Identification:
A. When strongly heated, a sample assumes a yellow color that disappears on cooling.
B. A solution of sample in a slight excess of 3 N hydrochloric acid gives positive tests for Zinc, Appendix IIIA.
Assay: Not less than 99.0% of ZnO after ignition.
Alkalinity: Passes test.
Cadmium: Not more than 3 mg/kg.
Lead: Not more than 10 mg/kg.
Loss on Ignition: Not more than 1.0%.
Substances Not Precipitated by Sulfide: Not more than 0.5%.

We also manufacture and supply Micro-Encapsulated Zinc Oxide, having core os zinc oxide and coating of vegetable oil or mono and diglycerides or as desired by the buyer.
