CAS No.: 7446-20-0 & 7733-02-0, EC Code EINECS: 231-793-3, Molecular Weight: 287.54 Heptahydrate, Chemical Formula: ZnSO4-7H2O Heptahydrate
Zinc Sulfate USP Grade Specifications
ZnSO4-xH2O.
Sulfuric acid, zinc salt (1:1), hydrate.
Zinc sulfate (1:1) monohydrate 179.46
Zinc sulfate (1:1) heptahydrate 287.56 [CAS 7446-20-0]
Anhydrous 161.46 [CAS 7733-02-0]
Zinc Sulfate contains one or seven molecules of water of hydration. The monohydrate contains not less than 89.0 percent and not more than 90.4 percent of ZnSO4, corresponding to not less than 99.0 percent and not more than 100.5 percent of ZnSO4·H2O, and the heptahydrate contains not less than 55.6 percent and not more than 61.0 percent of ZnSO4, corresponding to not less than 99.0 percent and not more than 108.7 percent of ZnSO4·7H2O.
Identification: A solution of it responds to the tests for Zinc and for Sulfate.
Acidity: A solution containing the equivalent of 28 mg of ZnSO4 per mL is not colored pink by methyl orange.
Arsenic: the limit is 14 ppm.
Lead: The lead limit is 0.002%.
Alkalies and alkaline earths: Dissolve the equivalent of 1.12 g of ZnSO4 in about 150 mL of water contained in a 200-mL volumetric flask. Precipitate the zinc completely by means of ammonium sulfide TS, and dilute with water to volume. Mix, and filter through a dry filter, rejecting the first portion of the filtrate. To 100 mL of the subsequent filtrate add a few drops of sulfuric acid, evaporate to dryness in a tarred dish, and ignite: the weight of the residue does not exceed 5 mg (0.9%).

CAS: monohydrate 7446-19-7
CAS: heptahydrate 7446-20-0
DESCRIPTION
Zinc Sulfate occurs as colorless, transparent prisms or small needles, or as a granular, crystalline powder. It contains one or seven molecules of water of hydration. The monohydrate loses water at temperatures above 238°; the heptahydrate effloresces in dry air at room temperature. Its solutions are acid to litmus. The monohydrate is soluble in water and practically insoluble in alcohol. One gram of the heptahydrate dissolves in about 0.6 mL of water and in about 2.5 mL of glycerin; it is insoluble in alcohol.
Function: Nutrient.
REQUIREMENTS
Identification: A 1:20 aqueous solution gives positive tests for Zinc and for Sulfate.
Assay: Monohydrate: Not less than 98.0% and not more than 100.5% of ZnSO4·H2O; Heptahydrate: Not less than 99.0% and not more than 108.7% of ZnSO4·7H2O.
Acidity: Passes test.
Alkalies and Alkaline Earths: Not more than 0.5%.
Cadmium: Not more than 2 mg/kg.
Lead: Not more than 4 mg/kg.
Mercury: Not more than 5 mg/kg.
Selenium: Not more than 0.003%.
