Magnesium Phosphate USP
Magnesium Phosphate
Mg3(PO4)2·5H2O 352.93
Phosphoric acid, magnesium salt (2:3),
pentahydrate.
Magnesium phosphate (3:2)
pentahydrate [10233-87-1].
Anhydrous 262.86 [7757-87-1].
Magnesium Phosphate, ignited at 425 to constant weight, contains
not less than 98.0 percent and not more than 101.5 percent of
Mg3(PO4)2.
Identification—
A: Dissolve about 200 mg in 10 mL of 2 N nitric acid, and add,
drop wise, ammonium molybdate TS: a greenish yellow precipitate of ammonium
phosphomolybdate is formed and it is soluble
in 6 N ammonium hydroxide.
B: Dissolve 0.1 g in 0.7
mL of 1 N
acetic acid and 20 mL of water. Add 1
mL of ferric chloride TS, allow
to stand for 5 minutes, and filter: 5
mL of the filtrate responds to the test for
Magnesium.
Microbial limits— It meets the requirements
of the test for absence of Escherichia coli.
Loss on ignition— Ignite it at 425 to constant weight: it
loses between 20.0% and 27.0% of its weight.
Acid-insoluble substances— If an
insoluble residue remains in the test for Carbonate, filter the
solution, wash well with hot water until the last washing is free from
chloride, and ignite the residue: the weight of the residue does not
exceed 4 mg (0.2%).
Soluble substances— Digest 2.0 g with 100 mL
of water on a steam bath for 30 minutes, cool, add sufficient water to
restore the original volume, mix, and filter. Evaporate 50
mL of the filtrate to dryness, and ignite
gently to constant weight: the weight of the residue does not exceed 15
mg (1.5%).
Carbonate— Mix 2.0 g with 20 mL of
water, and add hydrochloric acid, drop wise,
to effect solution: no effervescence occurs when the acid is added.
Chloride— Dissolve 0.50 g in 50
mL of
2 N nitric acid, and add 1 mL of silver
nitrate TS: the turbidity does not exceed that produced by 1.0
mL of 0.020 N hydrochloric acid (0.14%).
Limit of nitrate— Mix 0.20 g with 5
mL
of water, and add just sufficient hydrochloric acid to effect solution.
Dilute with water to 10 mL, add 0.1
mL of indigo carmine TS, then add, with stirring, 10mL of sulfuric acid: the blue color
persists for not less than 5 minutes.
Sulfate— Dissolve 0.50 g in the smallest possible amount of 3 N
hydrochloric acid, dilute with water to 48 mL,
and add 2 mL of barium chloride TS: the
turbidity does not exceed that produced by 3.0 mL
of 0.020 N sulfuric acid (0.6%).
Arsenic—The limit is 3
ppm.
Barium— Mix 2.0 g with 40 mL of
water, heat, add hydrochloric acid, drop wise,
to effect solution, and then add 1 mL of
acid in excess. Cool, dilute with water to 50 mL,
and filter. To 5 mL of the filtrate add 1
mL of potassium sulfate TS: no turbidity is
produced within 15 minutes.
Calcium— Mix 0.50 g with 15 mL of
water, heat, and add sufficient hydrochloric acid, in small portions, to
effect solution. Cool, add 6 N ammonium hydroxide, in small portions, to
produce a slight permanent precipitate, then
add 2 mL of 6 N acetic acid. Dilute with
water to 25 mL, and filter. To 10
mL of the filtrate add 2
mL of ammonium oxalate TS: not more than a
slight turbidity is produced within 5 minutes.
Dibasic salt and magnesium oxide— Ignite about 2.5 g to constant
weight. Weigh accurately about 2 g of ignited salt, and dissolve it by
warming with 50.0 mL of 1 N hydrochloric
acid VS. Cool, add 1 or 2 drops of methyl orange TS, and slowly titrate
the excess 1 N hydrochloric acid VS with 1 N sodium hydroxide VS to a
yellow color, vigorously shaking the mixture during the titration.
Between 14.8 and 15.4 mL of 1 N hydrochloric
acid is consumed for each g of the ignited salt.
Lead— the limit is 5
ppm.
Heavy metals— the limit is 0.003%.
Magnesium Phosphate, Dibasic, Mixed Hydrates FCC
MgHPO4·xH2O
DESCRIPTION
Magnesium Phosphate, Dibasic, Mixed Hydrates, occurs as a white,
crystalline powder that is a partially dehydrated form of a mixture of
magnesium phosphate, dibasic—in the trihydrate,
dihydrate, and anhydrous forms—and of
magnesium pyrophosphate. It is slightly soluble in water and insoluble
in alcohol, but is soluble in dilute acids.
Function: Nutrient; leavening agent; pH control agent.
