Potassium Metabisulfite USP Grade Specifications
K2S2O5 222.33
Disulfurous acid, dipotassium salt.
Dipotassium pyrosulfite [CAS 16731-55-8].
Potassium Metabisulfite contains an amount of K2S2O5 equivalent to not less than 51.8 percent and not more than 57.6 percent of SO2.
Identification— A solution (1 in 20) responds to the tests for Potassium and for Sulfite.
Iron— Dissolve 1.00 g in 14 mL of dilute hydrochloric acid (2 in 7), and evaporate on a steam bath to dryness. Dissolve the residue in 7 mL of dilute hydrochloric acid (2 in 7), and again evaporate to dryness. Dissolve the resulting residue in a mixture of 2 mL of hydrochloric acid and 20 mL of water, add 3 drops of bromine TS, and boil to expel the bromine. Cool, and dilute with water to 47 mL: the limit is 0.001%.
Heavy metals— Dissolve 2 g in 20 mL of water, add 5 mL of hydrochloric acid, evaporate on a steam bath to about 1 mL, and dissolve the residue in 25 mL of water: the limit is 0.001%.
Potassium Metabisulphite BP Ph Eur Grade Specifications
K2S2O5 - 222.3 - CAS 16731-55-8
DEFINITION
Potassium metabisulphite (potassium disulphite).
Content:
95.0 per cent to 101.0 per cent.
CHARACTERS
Appearance :
White or almost white powder, or colourless crystals.
Solubility:
Freely soluble in water, slightly soluble in ethanol (96 per cent).
IDENTIFICATION
A. pH (see Tests).
B. To 5 ml of solution S (see Tests), add 0.5 ml of 0.05 M iodine. The mixture is colourless and gives reaction of sulphates.
C. Solution S gives reaction of potassium.
TESTS
Solution S:
Dissolve 5.0 g in carbon dioxide-free water R and dilute to 100 ml with the same solvent.
Appearance of solution:
Solution S is clear and colourless.
pH:
3.0 to 4.5 for solution S.
Thiosulphates:
To 2.00 g add 25 ml of a 42.5 g/l solution of sodium hydroxide and 75 ml of water. Shake until dissolved and add 10 ml of formaldehyde and 10 ml of acetic acid. After 5 min, titrate with 0.05 M iodine using 1 ml of starch solution. Carry out a blank titration. The difference between the volumes consumed in the 2 titrations is maximum 0.15 ml.
Iron:
Maximum 10 ppm.
Selenium: Maximum 10 ppm.
Zinc: Maximum 25 ppm.
Heavy metals:
Maximum 10 ppm.
Potassium Metabisulfite FCC Food Grade Specifications
Potassium Pyrosulfite
