Approximately 1.5 million tons were produced in 1985, typically by the reaction of potassium chloride with sulfuric acid, analogous to the Mannheim process for producing sodium sulfate. [7] The process involves intermediate formation of potassium bisulfate, an exothermic reaction that occurs at room temperature: KCl + H 2 SO 4 → HCl + KHSO 4
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Potassium chloride – KCl; Potassium chlorite – KClO 2; Potassium chromate – K 2 CrO 4; Potassium cyanide – KCN; Potassium dichromate – K 2 Cr 2 O 7; Potassium dithionite – K 2 S 2 O 4; Potassium ferrate – K 2 FeO 4; Potassium ferrioxalate – K 3 [Fe(C 2 O 4) 3] Potassium ferricyanide – K 3 [Fe(CN)] 6; Potassium ferrocyanide ...

The relevant conversion is the exothermic reaction of potassium chloride and sulfuric acid: [1] [2] KCl + H 2 SO 4 → HCl + KHSO 4. Potassium bisulfate is a by-product in the production of nitric acid from potassium nitrate and sulfuric acid: [3] KNO 3 + H 2 SO 4 → KHSO 4 + HNO 3
Potassium chlorate can be produced in small amounts by disproportionation in a sodium hypochlorite solution followed by metathesis reaction with potassium chloride: [7] 3 NaOCl → 2 NaCl + NaClO 3 KCl + NaClO 3 → NaCl + KClO 3. It can also be produced by passing chlorine gas into a hot solution of caustic potash: [8] 3 Cl 2 + 6 KOH → KClO ...
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt -like taste.
