- Potassium Sulfate - Wikipedia
- Potassium sulfate (K2SO4) (in British English potassium sulphate, also called sulphate of potash, arcanite, or archaically known as potash of sulfur)
- Commonly used in fertilizers
- It does not form a hydrate, unlike sodium sulfate
- It is sometimes used as an alternative blast media similar to soda in soda blasting as it is harder and similarly water-soluble.
- Solubility in water 111 g/L (20 °C), 120 g/L (25 °C), 240 g/L (100 °C)
- do not confuse with potassium sulfide or liver of sulphur
