Knowra Potassium sulfate Potassium sulfate Potassium sulfate (K₂SO₄) is an inorganic salt that supplies potassium and sulfur. It is used chiefly as a fertilizer, especially where chloride exposure is undesirable.
Sulfate of potash : A commercial fertilizer consisting chiefly of potassium sulfate. This is the fertilizer trade name for potassium sulfate.
Potassium : A chemical element with symbol K and atomic number 19, essential to living cells and widely used in compounds. Potassium sulfate releases potassium ions that plants use for growth and physiological regulation.
Chemical formula : A symbolic notation showing the elements and relative numbers of atoms in a substance. K₂SO₄ shows that each formula unit contains two potassium atoms for every sulfate group.
Arcanite : The naturally occurring mineral form of potassium sulfate, K₂SO₄. Arcanite is the mineral counterpart of the compound sold as potassium sulfate.
Potassium nitrate : An ionic compound, KNO₃, used as a soluble potassium and nitrate fertilizer. It supplies nitrogen instead of sulfur and is more water-soluble.
Potassium chloride : An ionic compound, KCl, widely used as a potassium fertilizer and industrial chemical. It is usually cheaper, but adds chloride that some crops and soils cannot tolerate.
Sulfate : A polyatomic ion, SO₄²⁻, consisting of one sulfur atom bonded to four oxygen atoms. Sulfate is the counterion and sulfur source in potassium sulfate.
Molar mass : The mass of one mole of a substance, usually expressed in grams per mole. Its molar mass supports fertilizer nutrient calculations and chemical preparation.
Langbeinite : A mineral composed chiefly of potassium magnesium sulfate, K₂Mg₂(SO₄)₃. Processing langbeinite can produce potassium sulfate alongside magnesium-bearing products.
Potassium phosphate : A family of potassium salts containing phosphate ions, used in fertilizers and other applications. These salts supply phosphorus rather than the sulfur supplied by potassium sulfate.
