Specifications of Potassium Sulphate BP Ph Eur Grade
K2SO4
174.3 -- CAS Number 7778-80-5
Ph Eur

DEFINITION
Content: 98.5 per cent to 101.0 per cent of K2SO4 (dried substance).

CHARACTERS
Appearance: White or almost white, crystalline powder or colourless crystals.
Solubility: Soluble in water, practically insoluble in ethanol.

IDENTIFICATION
A. It gives the reactions of sulphates (2.3.1).
B. It gives the reactions of potassium (2.3.1).

TESTS
Solution S: Dissolve 10.0 g in 90 ml of carbon dioxide-free water prepared from distilled water, heating gently. Allow to cool and dilute to 100 ml with carbon dioxide-free water prepared from distilled water.
Appearance of solution: Solution S is clear and colourless.
Acidity or alkalinity: To 10 ml of solution S add 0.1 ml of bromothymol blue solution. Not more than 0.5 ml of 0.01 M hydrochloric acid or 0.01 M sodium hydroxide is required to change the colour of the
indicator.
Chlorides: Maximum 40 ppm.
Calcium: Maximum 200 ppm.
Iron: Maximum 10 ppm, determined on 10 ml of solution S.
Magnesium: Maximum 20 ppm.
Sodium: Maximum 0.10 per cent.
Atomic emission spectrometry: To pass the test..
Heavy metals: Maximum 20 ppm.
Loss on drying: Maximum 1.0 per cent, determined on 1.000 g by drying in an oven at 130 °C for 4 h.

ASSAY
Dissolve 0.150 g in 40 ml of water R. Add 0.2 ml of 0.1 M hydrochloric acid and 80 ml of
methanol R. Carry out a potentiometric titration (2.2.20), using 0.1 M lead nitrate and as
indicator electrode a lead-selective electrode and as reference electrode a silver-silver
chloride electrode.
1 ml of 0.1 M lead nitrate is equivalent to 17.43 mg of K2SO4.
