Sodium Perborate BP Ph Eur Specifications
NaBH2O4-3H2O --- 153.9 --- CAS 7632-04-4
NaBH2O4-3H2O = NaB4O3-4H2O
DEFINITION
Content: 96.0 per cent to 103.0 per cent.
CHARACTERS
Appearance: Colourless, prismatic crystals or white or almost white powder, stable in the crystalline form.
Solubility: Sparingly soluble in water, with slow decomposition. It dissolves in dilute mineral acids.
IDENTIFICATION
A. Mix 1 ml of a saturated solution with a mixture of 1 ml of dilute sulphuric acid and 0.2ml of a 70 g/l solution of potassium dichromate, shake with 2 ml of ether and allow to stand. A blue colour is produced in the ether layer.
B. The mixture obtained by treating about 100 mg with 0.1 ml of sulphuric acid and 5 ml of methanol burns with a greenish flame when ignited.
C. It gives reaction of sodium.
