Magnesium Hydroxide
CAS Number: 1309-42-8
Molecular Formula: Mg(OH)2
Molecular Weight: 58.32
Magnesium Hydroxide
Magnesium Hydroxide USP Grade Specifications
Magnesium Hydroxide
Mg(OH)2 58.32
Magnesium hydroxide.
Magnesium hydroxide CAS 1309-42-8
Magnesium Hydroxide, dried at 105 for 2 hours, contains not less than 95.0 percent and not more than 100.5 percent of Mg(OH)2.
Identification: A 1 in 20 solution in 3 N hydrochloric acid responds to the tests for Magnesium.
Microbial limits: It meets the requirements of the test for absence of Escherichia coli.
Loss on drying: Dry it at 105 for 2 hours: it loses not more than 2.0% of its weight.
Loss on ignition: Ignite it at 800 , increasing the heat gradually, to constant weight: it loses between 30.0% and 33.0% of its weight.
Soluble salts: Boil 2.0 g with 100 mL of water for 5 minutes in a covered beaker, filter while hot, cool, and dilute the filtrate with water to 100 mL. Titrate 50 mL of the diluted filtrate with 0.10 N sulfuric acid, using methyl red TS as the indicator: not more than 2.0 mL of the acid is consumed.
Evaporate 25 mL of the diluted filtrate to dryness, and dry at 105 for 3 hours: not more than 10 mg of residue remains.
Carbonate: Boil a mixture of 0.10 g with 5 mL of water, cool, and add 5 mL of 6 N acetic acid: not more than a slight effervescence is observed.
Limit of calcium: the limit is 1.5%.
Heavy metals: the limit is 20 <g per g.
Lead: limit is 0.001%.
