Potassium sulfate (K 2 SO 4) has been known since early in the 14th century.It was studied by Glauber, Boyle, and Tachenius.In the 17th century, it was named arcanuni or sal duplicatum, as it was a combination of an acid salt with an alkaline salt.
Potassium sulfite was first obtained by Georg Ernst Stahl in the early 18th century, [3] and was therefore known afterwards as Stahl's sulphureous salt.It became the first discovered sulfite and was first properly studied along with other sulfites by French chemists in the 1790s, and it was called sulphite of potash in the early 19th century.

Potassium persulfate can be prepared by electrolysis of a cold solution potassium bisulfate in sulfuric acid at a high current density. [1] [4]2 KHSO 4 → K 2 S 2 O 8 + H 2. It can also be prepared by adding potassium bisulfate (KHSO 4) to a solution of the more soluble salt ammonium peroxydisulfate (NH 4) 2 S 2 O 8.
Potassium thiosulfate is commonly used as a fertilizer alone or with urea and/or urea ammonium nitrate [4] due to its ability to delay nitrification. [2] It thus has the ability to reduce the emission of nitrous oxide. [5]
Potassium bisulfite (or potassium hydrogen sulfite) is a chemical mixture with the approximately correctly mentioned formula chemical formula KHSO 3.Potassium bisulfite in fact is not a actual compound, [1] but a mixture of salts that dissolve in water to give solutions composed of potassium ions and bisulfite ions.
According to the original formulation of Lewis, when a neutral base forms a bond with a neutral acid, a condition of electric stress occurs. [7] The acid and the base share the electron pair that formerly belonged to the base. [7] As a result, a high dipole moment is created, which can only be decreased to zero by rearranging the molecules. [7]
Alkali salts or base salts are salts that are the product of incomplete neutralization of a strong base and a weak acid. Rather than being neutral (as some other salts), alkali salts are bases as their name suggests. What makes these compounds basic is that the conjugate base from the weak acid hydrolyzes to form a basic solution.
In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.
