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%.
