Borax BP

Borax BP; Sodium Borate; Sodium Tetraborate
Na2B4O7,10H2O -- 381.4 -- 1303-96-4

DEFINITION
Borax contains not less than 99.0 per cent and not more than the equivalent of 103.0  per cent of disodium tetraborate decahydrate.

CHARACTERS
A white, crystalline powder, colourless crystals or crystalline masses, efflorescent, soluble in water, very soluble in boiling water, freely soluble in glycerol.

IDENTIFICATION
A. To 1 ml of solution S (see Tests) add 0.1 ml of sulphuric acid and 5 ml of methanol \ and ignite. The flame has a green border.
B. To 5 ml of solution S add 0.1 ml of phenolphthalein solution. The solution is red. On the addition of 5 ml of glycerol (85 per cent) the colour disappears.
C. Solution S gives the reactions of sodium.

TESTS
Solution S
Dissolve 4.0 g in carbon dioxide-free water prepared from distilled water and  dilute to 100 ml with the same solvent.
Appearance of solution
Solution S is clear and colourless.
pH
The pH of solution S is 9.0 to 9.6.
Sulphates
15 ml of solution S complies with the limit test for sulphates (50 ppm).
Ammonium
6 ml of solution S diluted to 14 ml with water complies with the limit test for  ammonium (10 ppm).
Arsenic
5 ml of solution S complies with limit test A for arsenic (5 ppm).
Calcium
15 ml of solution S complies with the limit test for calcium (100 ppm).
Heavy metals
12 ml of solution S complies with limit test A for heavy metals (25 ppm).

Boric Acid BP

DEFINITION
Boric acid contains not less than 99.0 per cent and not more than the equivalent of 100.5 percent of H3BO3.

CHARACTERS
A white, crystalline powder, colourless, shiny plates greasy to the touch, or white  crystals, soluble in water and in alcohol, freely soluble in boiling water and in glycerol  (85 per cent).

IDENTIFICATION
A. Dissolve 0.1 g by gently heating in 5 ml of methanol, add 0.1 ml of sulphuric acid and ignite the solution. The flame has a green border.
B. Solution S (see Tests) is acid.

TESTS
Solution S
Dissolve 3.3 g in 80 ml of boiling distilled water, cool and dilute to 100 ml with  carbon dioxide-free water prepared from distilled water.
Appearance of solution
Solution S is clear and colourless.
pH
The pH of solution S is 3.8 to 4.8.
Solubility in alcohol
Dissolve 1.0 g in 10 ml of boiling alcohol. The solution is not more opalescent than reference suspension and is colourless.
Organic matter
It does not darken on progressive heating to dull redness.
Sulphates
10 ml of solution S diluted to 15 ml with distilled water complies with the limit test  for sulphates (450 ppm).
Heavy metals
12 ml of solution S complies with limit test A for heavy metals (15 ppm).
