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).

Borax
Borax [1303-96-4]
Anhydrous 201.22 [1330-43-4]
Sodium Borate contains an amount of Na2B4O7 equivalent to not less than 99.0 percent and not more than 105.0 percent of Na2B4O7·10H2O.
Identification—
A solution (1 in 20) responds to the tests for Sodium and for Borate.
Carbonate and bicarbonate— To 5 mL of a solution (1 in 20), contained in a
test tube, add 1 mL of 3 N hydrochloric acid: no effervescence is observed.
Heavy metals— the limit is 0.002%.
