British Pharmacopoeia
Calcium Hydroxide BP Ca(OH)2
Calcium Hydroxide BP British
Pharmacopoeia
Ca(OH)2 ıı74.1ıı
Preparation
Calcium 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.
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 [1305-62-0].
Calcium
Hydroxide contains not less than 95.0 percent and not more than 100.5 percent of
Ca(OH)2.
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.

I shall pass through this world, but once. If therefore, there is any good that I can do, or if there is any favour that I can show to a fellow human being, let me do it now. Let me not defer or neglect it. For I shall not tread this way again.

Barter
They who love thee on this earth, keep calling on thee
and chanting thy beads
Lest thou forgetest.
They assign the credit of their hard work to your
blessings
They keep you amused.
They come to thy temple with baskets of fruits, as if you
were a glutton
They deny the same to their children.
They offer you milk for a bath and burn the ghee
They hardly understand the meaning of it.
They bring gold and diamonds. They come with beating of
drums
They love to advertise their offerings.
They offer you a small bribe as advance for booty, called
lottery
They love to dream.
I do not bow down at your door
I do not bargain for booty
Your promise of the heaven does not lure me
Your hell-fire does not scare me
I do not even know the proper method of prayer
I do not offer any thing to you
Ages have gone by and I have not seen you my lord
Yet my love for you keeps waiting for you
