Specifications of Boric Acid USP NF Grade
H3BO3 -- 61.83
H3BO3 CAS 10043-35-3
Boric Acid contains not less than 99.5 percent and not more than 100.5 percent of H3BO3, calculated on the dried basis.
Solubility in alcohol: One g dissolves completely in 10 mL of boiling alcohol.
Completeness of solution: One g dissolves in 25 mL of water, producing a clear solution.
Identification: It responds to the tests for Borate.
Loss on drying: Dry it over silica gel for 5 hours: it loses not more than 0.5% of its weight.
Heavy metals: Dissolve 1 g in 23 mL of water, and add 2 mL of 1 N acetic acid: the limit is 0.002%.

H3BO3 -- 61.8 -- CAS 10043-35-3
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.
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).
