Boric Acid BP
H3BO3 -- 61.8 -- 10043-35-3
Boric Acid BP
DEFINITION
Boric acid contains not less than 99.0 per cent and not more than the
equivalent of 100.5 percent of H3BO3.
CHARACTERS
A white, crystalline powder, colourless, shiny plates greasy to the
touch, or white crystals, soluble in water and in alcohol, freely soluble
in boiling water and in glycerol (85 per cent).
IDENTIFICATION
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.
TESTS
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).
Boric Acid USP NF
H3BO3 -- 61.83
Boric acid
USP-NF (H3BO3) [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%.
