Na2B4O7-10H2O --- 381.37 --- [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%.
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 PhPh 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.
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.
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).
