Ferrous Sulfate USP Grade Specifications
FeSO4-7H2O -- 278.02
Sulfuric acid, iron(2+) salt (1:1), heptahydrate.
Iron(2+) sulfate (1:1) heptahydrate CAS 7782-63-0
Anhydrous 151.91 CAS 7720-78-7
Ferrous Sulfate contains an amount of FeSO4 equivalent to not less than 99.5 percent and not more than 104.5 percent of FeSO4-7H2O.
Identification: It responds to the tests for Ferrous Salts 191 and for Sulfate 191 .
Arsenic: Transfer 1.0 g to a round-bottom, 100-mL flask fitted with a glass joint, add 40 mL of 9 N sulfuric acid and 2 mL of potassium bromide solution (3 in 10), and immediately connect the flask to a condenser having a matching glass joint and a reservoir with a water jacket that is cooled by ice-water. Heat the flask gently over a low flame until the solid dissolves, then distill until 25 mL of distillate collects in the reservoir. Transfer this distillate to the arsine generator flask, and wash the condenser and the reservoir with several small portions of water, adding the washings to the generator flask. Swirl to mix, add bromine until the color of the solution is slightly yellow, and dilute with water to 35 mL. The limit is 3 ppm.
Lead: the limit is 0.001%.
Mercury: It meets the requirement.

Iron(2+) sulfate (1:1) hydrate CAS 13463-43-9
Anhydrous 151.91 CAS 7720-78-7
Dried Ferrous Sulfate contains not less than 86.0 percent and not more than 89.0 percent of anhydrous ferrous sulfate (FeSO4).
Identification: It responds to the tests for Ferrous and Sulfate..
Insoluble substances: Dissolve 2.0 g in 20 mL of freshly boiled dilute sulfuric acid (1 in 100), heat to boiling, and digest in a covered beaker on a steam bath for 1 hour. Filter through a tared filtering crucible, wash thoroughly, and dry at 105C: the weight of the insoluble residue does not exceed 1 mg (0.05%).
Arsenic: It meets the requirements of the test for Arsenic under Ferrous Sulfate.
Lead: the limit is 0.001%.
Mercury: It meets the requirements.
Ferrous Sulfate FCC Food Grade Specifications
FeSO4-7H2O Formula weight 278.02
CAS 7782-63-0
DESCRIPTION
Ferrous Sulfate occurs as pale, blue-green crystals or granules that are efflorescent in dry air. In moist air, it oxidizes readily to form a brown-yellow, basic ferric sulfate. A 1:10 aqueous solution has a pH of about 3.7. One gram dissolves in 1.5 mL of water at 25° and in 0.5 mL of boiling water. It is insoluble in alcohol.
Function: Nutrient.
REQUIREMENTS
Identification: A sample gives positive tests for Ferrous Salts (Iron) and for Sulfate.
Assay: Not less than 99.5% and not more than 104.5% of FeSO4-7H2O.
Lead: Not more than 2 mg/kg.
Mercury: Not more than 1 mg/kg.
