Basic Info

Model No.: food grade heptahydrate

Product Description


Magnesium Sulfate

Other name : Epsom Salt

Molecular Formula : MgSO4·xH2O

Molecular Weight : Monohydrate 138.38

Molecular Weight : Heptahydrate 246.47

INS: 518

CAS: monohydrate [14168-73-1]

CAS: heptahydrate [10034-99-8]

CAS: dried [15244-36-7]

DESCRIPTION

Magnesium Sulfate occurs as a colorless crystal or a granular crystalline powder. It is produced with one or seven molecules of water of hydration or in a dried form containing the equivalent of about 2.3 waters of hydration. It is readily soluble in water, slowly soluble in glycerine, and sparingly soluble in alcohol.

Function : Nutrient.

REQUIREMENTS

Labeling

Indicate whether it is the monohydrate, the heptahydrate, or the dried form.

Identification

A 1:20 aqueous solution gives positive tests for Magnesium and for Sulfate, Appendix IIIA.

Assay

Not less than 99.5% of MgSO4 after ignition.

Lead

Not more than 4 mg/kg.

Loss on Ignition

Monohydrate: Between 13.0% and 16.0%; Heptahydrate: Between 40.0% and 52.0%; Dried: Between 22.0% and 28.0%.

Selenium

Not more than 0.003%.

TESTS

Assay

Accurately weigh about 500 mg of the residue obtained in the test for Loss on Ignition (below), dissolve it in a 1:50 mixture of hydrochloric acid:water, dilute with water to 100.0 mL, and mix. Transfer 50.0 mL of this solution into a 250-mL Erlenmeyer flask, add 10 mL of ammonia– ammonium chloride buffer TS and 12 drops of eriochrome black TS, and titrate with 0.1 M disodium EDTA until the wine red color changes to pure blue. Each milliliter of 0.1 M disodium EDTA is equivalent to 12.04 mg of MgSO4.

Lead

Determine as directed in the APDC Extraction Method under Lead Limit Test, Appendix IIIB.

Loss on Ignition

Transfer about 1 g of sample, accurately

weighed, and transfer it into a crucible, heat at 105° for 2 h, and then ignite in a muffle furnace at 450°±25° to constant weight.

Selenium

Determine as directed in Method II under Selenium Limit Test, Appendix IIIB, using 200 mg of sample.

Packaging and Storage

Store in well-closed containers.
