Borax BP; Sodium Borate; Sodium Tetraborate
Na2B4O7,10H2O -- 381.4 -- 1303-96-4
Borax contains not less than 99.0 per cent and not more than the equivalent of 103.0 per cent of disodium tetraborate decahydrate.
A white, crystalline powder, colourless crystals or crystalline masses, efflorescent, soluble in water, very soluble in boiling water, freely soluble in glycerol.
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.
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.
The pH of solution S is 9.0 to 9.6.
15 ml of solution S complies with the limit test for sulphates (50 ppm).
6 ml of solution S diluted to 14 ml with water complies with the limit test for ammonium (10 ppm).
5 ml of solution S complies with limit test A for arsenic (5 ppm).
15 ml of solution S complies with the limit test for calcium (100 ppm).
12 ml of solution S complies with limit test A for heavy metals (25 ppm).
