Manganese Chloride FCC Grade Specifications
MnCl2 Formula wt, anhydrous 125.84
MnCl2·4H2O Formula wt, tetrahydrate 197.91
CAS: anhydrous [CAS 7773-01-5]
CAS: tetrahydrate [CAS 13446-34-9]
DESCRIPTION
It occurs as large, irregular, pink, translucent crystals. It is freely soluble in water at room temperature and very soluble in hot water.
Function: Nutrient.
REQUIREMENTS
Identification: A 1:20 aqueous solution gives positive tests for Manganese and for Chloride.
Assay: Not less than 98.0% and not more than 102.0% of MnCl2·4H2O.
Insoluble Matter: Not more than 0.005%.
Iron: Not more than 5 mg/kg.
Lead: Not more than 4 mg/kg.
pH of a 5% Solution: Between 4.0 and 6.0.
Substances Not Precipitated by Sulfide: Not more than 0.2%, after ignition.
Sulfate: Not more than 0.005%.
Manganese Chloride Tetrahydrate USP Grade Specifications
MnCl2.4H2O --- 197.90
Manganese (2+) chloride tetrahydrate [CAS 13446-34-9].
Anhydrous 125.84 [CAS 7773-01-5].
Manganese Chloride contains not less than 98.0 percent and not more than 101.0 percent of MnCl2, calculated on the dried basis.
Identification:
A: Yields white, curdy precipitate of silver chloride with silver nitrate TS, which is insoluble in nitric acid. After being washed with water, this precipitate is soluble in a slight excess of 6 N ammonium hydroxide.
B: It meets the requirements of the test for Manganese.
pH: between 3.5 and 6.0, 10 g dissolved in 200 mL of carbon dioxide- and ammonia-free water being used.
Loss on drying: Dry it at 50 for 2 hours, then raise the temperature to 150 for 24 hours: it loses between 36.0% and 38.5% of its weight.
Insoluble matter: Transfer 10 g to a 250-mL beaker, add 150 mL of water, cover the beaker, and heat to boiling. Digest the hot solution on a steam bath for 1 hour, and pass through a tared, fine-porosity filtering crucible. Rinse the beaker with hot water, passing the rinsings through the filter, and finally wash the filter with additional hot water. Dry the filter at 105C: the residue weighs not more than 0.5 mg (0.005%).
Sulfate: To pass the test (0.2% as sulfate).
Iron: Dissolve 2.0 g in 40 mL of water: the limit is 5 µg per g.
Zinc: Dissolve 1 g in a mixture of 48 mL of water and 2 mL of sulfuric acid, and add, slowly and with constant agitation, 1 mL of potassium ferrocyanide solution (1 in 100): no turbidity is produced within 5 minutes.
Heavy metals: the limit is 5 µg per g.
