Calcium Carbonate USP
CaCO3 100.09
Carbonic acid, calcium salt (1:1)
Calcium Carbonate, dried
at 200 for 4 hours, contains calcium equivalent to not less than 98.0
percent and not more than 100.5 percent of CaCO3.
Packaging and storage Preserve in well-closed containers.
Identification
The
addition of acetic acid to it produces effervescence (presence of
carbonate), and the resulting solution, after boiling, responds to the
tests for Calcium.
Loss on drying
Dry it at 200 for 4 hours: it loses not more than 2.0% of its weight.
Acid-insoluble
substances Mix 5.0 g with 10 mL of water, and add hydrochloric acid,
drop wise, with agitation, until it ceases to cause effervescence, then add
water to make the mixture measure 200 mL, and filter. Wash the insoluble
residue with water until the last washing shows no chloride, and ignite: the
weight of the residue does not exceed 10 mg (0.2%).
Limit of fluoride The limit is 0.005%.
Arsenic The limit is 3 ppm.
Barium A platinum
wire, dipped in the filtrate obtained in the test for Acid-insoluble
substances and held in a non-luminous flame, does not impart a green
color.
Lead the
limit is 3 ppm.
Iron To pass the
test
Mercury
the limit is 0.5 ΅g per g.
Limit of magnesium and
alkali salts Mix 1.0 g with 35 mL of water, carefully add 3 mL of hydrochloric acid, heat
the solution, and boil for 1 minute. Rapidly add 40 mL of oxalic acid TS,
and stir vigorously until precipitation is well established. Add immediately
to the warm mixture 2 drops of methyl red TS and then 6 N ammonium
hydroxide, drop wise, until the mixture is just alkaline. Cool to room
temperature, transfer to a 100-mL graduated cylinder, dilute with water to
100 mL, mix, and allow to stand for 4 hours or overnight. Filter, and to 50
mL of the clear filtrate in a platinum dish add 0.5 mL of sulfuric acid, and
evaporate the mixture on a steam bath to a small volume. Carefully heat over
a free flame to dryness, and continue heating to complete decomposition and
volatilization of ammonium salts. Finally ignite the residue to constant
weight.
The weight of the residue
does not exceed 5 mg (1.0%).
Heavy metals the limit is 0.002%.
Organic volatile
impurities meets the requirements.

DEFINITION
Content
98.5 per cent to 100.5 per cent (dried substance).
CHARACTERS
Appearance
White or almost white powder.
Solubility
Practically insoluble in water.
IDENTIFICATION
A. It gives the reaction of carbonates
B. 0.2 ml of solution S (see Tests) gives the reactions of calcium
TESTS
Solution S
Dissolve 5.0 g in 80 ml of
dilute acetic acid R . When the
effervescence ceases, boil for 2min. Allow to cool, dilute to 100 ml
with dilute acetic acid R and filter, if necessary, through a
sintered-glass filter.
Substances insoluble in
acetic acid
Maximum 0.2 per cent.
Chlorides
Maximum 330 ppm.
Sulphates
Maximum 0.25 per cent.
Arsenic
Maximum 4 ppm, determined
on 5 ml of solution S.
Barium
To 10 ml of solution S add 10 ml of calcium sulphate solution R . After
at least 15 min, any opalescence in the solution is not more intense than
that in a mixture of 10 ml of solution S and 10 ml of distilled water R.
Iron
Maximum 200 ppm.
Magnesium and alkali
metals
Maximum 1.5 per cent.
Heavy metals
Maximum 20 ppm.
Calcium Carbonate FCC as per US Food Chemical Codex
CaCO3 Formula wt 100.09
CAS:
[471-34-1]
DESCRIPTION
Calcium Carbonate occurs
as a fine, white or colorless, microcrystalline powder. It is stable in
air, and it is practically insoluble in water and in
alcohol. The presence of any ammonium salt or carbon dioxide
increases its solubility in water, but the presence of any
alkali hydroxide reduces the solubility.
Function: pH control
agent; nutrient; dough conditioner; firming agent; yeast
nutrient.
REQUIREMENTS
Identification: A
sample dissolves, with effervescence, in 1 N acetic acid, in
2.7 N hydrochloric acid, and in 1.7 N nitric acid, and the resulting
solutions, after boiling, give positive tests for Calcium.
Assay: Not less than
98.0% and not more than 100.5% of CaCO3 after drying.
Acid-Insoluble
Substances: Not more than 0.2%.
Arsenic: Not more
than 3 mg/kg.
Fluoride: Not more
than 0.005%.
Lead: Not more than
3 mg/kg.
Loss on Drying: Not
more than 2%.
Magnesium and Alkali
Salts: Not more than 1%.
