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
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. Potassium chloride can be obtained from ancient dried lake deposits. [7]
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 ...
Molecular models of the different molecules active in Piranha solution: peroxysulfuric acid (H 2 SO 5) and hydrogen peroxide (H 2 O 2). Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2).
For many substances, the formation reaction may be considered as the sum of a number of simpler reactions, either real or fictitious. The enthalpy of reaction can then be analyzed by applying Hess' law, which states that the sum of the enthalpy changes for a number of individual reaction steps equals the enthalpy change of the overall reaction.
In chemistry, a strong electrolyte is a solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution.
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
In chemistry and thermodynamics, the enthalpy of neutralization (ΔH n) is the change in enthalpy that occurs when one equivalent of an acid and a base undergo a neutralization reaction to form water and a salt. It is a special case of the enthalpy of reaction. It is defined as the energy released with the formation of 1 mole of water.
