Specifications of Calcium Hydroxide USP Grade
Calcium Hydroxide; Lime
Ca(OH)2 -- 74.09 --- CAS 1305-62-0.

Calcium Hydroxide contains not less than 95.0 percent and not more than 100.5 percent of Ca(OH)2.

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%).

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 phph 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.

Specifications of Calcium oxide USP or Lime USP Grade
Quick Lime, when freshly ignited to constant weight, contains not less than 95.0 percent of CaO, Calcium Oxide.

Identification:
A: Moisten it with water: heat is generated, and a white powder is obtained (calcium hydroxide or slaked lime). Mix the powder with 3 or 4 times its weight of water: a smooth magma of lime forms that is alkaline to litmus.
B: Slake 1 g of Lime or Calcium Oxide with 20 mL of water, and add 6 N acetic acid until the lime is dissolved: the resulting solution responds to the test for Calcium.
Loss on ignition: Ignite a portion of Quick Lime or Calcium Oxide to constant weight in a tarred platinum crucible at 1100±50C it loses not more than 10.0% of its weight.
Insoluble substances: Slake 5 g of Quick Lime or Calcium Oxide, then mix with 100 mL of water, followed by hydrochloric acid, drop wise, with agitation, until solution takes place: the resulting solution after boiling and cooling is acid, and when filtered through a tarred crucible, washed with water until free of chlorides, and dried at 105 for 1 hour yields not more than 50 mg of insoluble substances (1.0%).
Carbonate: Slake 1 g, mix with 50 mL of water, and decant the greater portion of the milky liquid: the addition of an excess of 3 N hydrochloric acid to the residue does not cause more than a slight effervescence.
Magnesium and alkali salts: Dissolve 500 mg in 30 mL of water and 15 mL of 3 N hydrochloric acid. Neutralize the solution with 6 N ammonium hydroxide, heat to boiling, and add ammonium oxalate TS to precipitate the calcium completely. Heat the mixture on a steam bath for 1 hour, cool, dilute with water to 100 mL, mix, and filter. To 50 mL of the filtrate add 0.5 mL of sulfuric acid, evaporate to dryness, and ignite in a tarred platinum crucible to constant weight. The weight of the residue does not exceed 9 mg.
