Sodium Borate or Borax USP NF BP Ph Eur IP ACS Reagent Manufacturers

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).
