DEFINITION
Content
95.0 per cent to 100.5 per cent.
CHARACTERS
Appearance
White or almost white, fine powder.
Solubility
Practically insoluble in water.
IDENTIFICATION
A. To 0.80 g in a mortar, add 10 ml of water R
and 0.5 ml of phenolphthalein solution and mix. The suspension turns red.
On addition of 17.5 ml of 1 M hydrochloric acid , the suspension becomes
colourless without effervescing. The red colour occurs again when the mixture is
triturated for 1 min. On addition of a further 6 ml of 1 M hydrochloric acid
and triturating, the solution becomes colourless.
B. Dissolve about 0.1 g in dilute hydrochloric acid
and dilute to 10 ml with water . 5 ml of the solution give reaction
of calcium.
TESTS
Matter insoluble in hydrochloric acid
Maximum 0.5 per cent.
Dissolve
2.0 g in 30 ml of hydrochloric acid. Boil the solution and filter. Wash
the residue with hot water. The residue weighs a maximum of 10 mg.
Carbonates
Maximum 5.0
per cent of CaCO3.
Chlorides
Maximum 330
ppm.
Sulphates
Maximum 0.4
per cent.
Arsenic
Maximum 4
ppm.
Magnesium and alkali metals
Maximum 4.0
per cent calculated as sulphates.
Heavy
metals
Maximum 20
ppm.
ASSAY
To 1.500 g
in a mortar, add 20-30 ml of
water R and 0.5 ml of phenolphthalein solution. Titrate with 1
M hydrochloric acid by triturating the substance until the red colour
disappears. The final solution is used in the tests for carbonates.
1 ml of
1 M hydrochloric acid
is equivalent to 37.05 mg of Ca(OH)2.
