KSO3F

KSO3F is the chemical formula for potassium fluorosulfate. It is an inorganic salt composed of potassium cations (K+) and fluorosulfate anions (SO3F-). This compound is a white crystalline solid under standard conditions. Potassium fluorosulfate is soluble in water, forming an acidic solution due to the hydrolysis of the fluorosulfate anion. Its preparation can be achieved through various synthetic routes, often involving reactions between potassium compounds and sources of the fluorosulfate group. For example, it can be formed by reacting potassium bisulfate with potassium fluoride under specific conditions, or by the reaction of sulfuryl fluoride with potassium hydroxide. KSO3F is known to decompose upon heating, releasing sulfuryl fluoride and potassium fluoride. It has found some applications in chemical synthesis and as a reagent in laboratory settings. Due to the presence of the fluorosulfate anion, which is a derivative of fluorosulfuric acid (HSO3F), potassium fluorosulfate exhibits some of the reactivity associated with strong acids and oxidizing agents. Its handling requires appropriate safety precautions due to its potential for irritation and decomposition.
