tight containers.
Identification
A: When mixed with from three to
four times its weight of water, it forms a smooth magma. The clear, supernatant
from the magma is alkaline to litmus.
B: Mix 1 g with 20 mL of water,
and add sufficient 6 N acetic acid to effect solution: the resulting solution
responds to the tests for Calcium 191.
Limit of acid-insoluble substances Dissolve 2.0 g in 30 mL of 4 N hydrochloric acid, and heat to boiling.
Filter the mixture, wash the residue with hot water, and ignite: the weight of
the residue does not exceed 10 mg (0.5%).
Carbonate Mix 2 g with 50 mL of
water: the addition of an excess of 3 N hydrochloric acid to the mixture does
not cause more than a slight effervescence.
Heavy metals Dissolve 2.0 g in 20
mL of 3 N hydrochloric acid, and evaporate on a steam bath to dryness. Dissolve
the residue in 20 mL of water, and filter. Dilute the filtrate with water to 40
mL, and to 20 mL of the resulting solution add 1 mL of 0.1 N hydrochloric acid,
then add water to make 25 mL: the limit is 20 6g per g.
Limit of magnesium and alkali salts Dissolve 0.50 g in a mixture of 30 mL of water and 10 mL of 3 N hydrochloric
acid, and proceed as directed in the test for Magnesium and alkali salts under
Calcium Carbonate, beginning with heat the solution, and boil for
1 minute. The weight of the residue does not exceed 12 mg (4.8%).
Assay Transfer about 1.5 g of
Calcium Hydroxide, accurately weighed, to a beaker, and gradually add 30 mL of 3
N hydrochloric acid. When the solution is dissolved, transfer it to a 500-mL
volumetric flask, rinse the beaker thoroughly, adding the rinsing to the flask,
dilute with water to volume, and mix. Pipette 50 mL of the solution into a
suitable container, add 100 mL of water, 15 mL of 1 N sodium hydroxide, and 300
mg of hydroxy naphthol blue, and titrate with 0.05 M edentate disodium VS to a
blue endpoint. Each mL of 0.05 M edetate disodium is equivalent to 3.705 mg of
Ca(OH)2.
