KClO2

Potassium chlorite, with the chemical formula KClO2, is an inorganic compound. It is the potassium salt of chlorous acid. Potassium chlorite is a white solid that is soluble in water. Like other chlorites, it is an oxidizing agent. It is not a very common compound and is typically synthesized rather than found naturally.

The synthesis of potassium chlorite can be achieved through various methods. One common route involves the reaction of potassium chlorate with sulfur dioxide in an aqueous solution. Another method involves the electrolysis of potassium chloride solutions under specific conditions. Careful control of reaction parameters is necessary due to the oxidizing nature of the compound and the potential for hazardous byproducts.

Potassium chlorite has limited practical applications compared to other potassium or chlorine compounds. Historically, there have been investigations into its use as a bleaching agent or in pyrotechnics, but these applications are not widespread. Its instability and reactivity, particularly when mixed with combustible materials, necessitate careful handling and storage. It is important to note that chlorite compounds can decompose when heated, potentially releasing oxygen and other gases. Therefore, it is not a widely used chemical in industrial processes.
