Potassium Sulfate occurs as colorless or white crystals or as a crystalline powder. One gram dissolves in about 8.5 mL of water. It is insoluble in alcohol. The pH of a 1:20 aqueous solution is about 5.5 to 8.5.
Identification:A 1:10 aqueous solution gives positive tests for Potassium, Appendix IIIA.
Assay: Not less than 99.0% and not more than 100.5% of K2SO4.
Lead: Not more than 2 mg/kg.
Selenium: Not more than 5 mg/kg.
Potassium Sulphate BP Grade
K2SO4 -- 174.3 -- 7778-80-5
Content: 98.5 per cent to 101.0 per cent of K2SO4 (dried substance).
Appearance: White or almost white, crystalline powder or colourless crystals.
Solubility: Soluble in water, practically insoluble in ethanol.
A. It gives the reactions of sulphates.
B. It gives the reactions of potassium.
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 R1. 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.

A jackal woke up early in the morning and went in to the plains. He looked at his long shadow in the rising morning sun and said to himself, "I must have a camel for my meal today".
He kept moving around till noon and it was getting hot and the jackal was tired. He was also hungry and thirsty. He looked at his small shadow in the mid-day sun. He murmered, "I was only joking about the camel, a mouse will do".
