Ca(OH)2 -- 74.1
PreparationCalcium Hydroxide Solution
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.
Calcium Hydroxide USP Ca(OH)2
Calcium Hydroxide; Lime
Ca(OH)2 -- 74.09
Calcium hydroxide [1305-62-0].
Calcium Hydroxide contains not less than 95.0 percent and not more than 100.5 percent of Ca(OH)2.
Packaging and storage Preserve in 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.
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.
