Preparation of antimony sulfate
20 g finely powdered antimony are added to 400 g of boiling concentrated sulfuric acid and boiled until antimony has dissolved. A part of the antimony sulfate crystallizes out of the hot solution, the rest upon the cooling of the liquid, in the form of small white needles. It is filtered washed twice with acetic acid, ether and dried in a vacuum desiccator over solid potassium or sodium hydroxide.
Alternatively anhydrous antimony sulfate could be prepared by dissolving the antimony trisulphide in boiling concentrated sulfuric acid. The antimony sulfate is deposited as a fine, very deliquescent, white crystallized powder.
