Toggle Chemical properties subsection. 3.1 Solubility. ... Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine.
Sylvite, or sylvine, is potassium chloride (KCl) in natural mineral form. It forms crystals in the isometric system very similar to normal rock salt, halite (NaCl). The two are, in fact, isomorphous. [5] Sylvite is colorless to white with shades of yellow and red due to inclusions. It has a Mohs hardness of 2.5 and a specific gravity of 1.99.
Most agricultural fertilizers contain potassium chloride, while potassium sulfate is used for chloride-sensitive crops or crops needing higher sulfur content. The sulfate is produced mostly by decomposition of the complex minerals kainite (MgSO 4 ·KCl·3H 2 O) and langbeinite (MgSO 4 ·K 2 SO 4). Only a very few fertilizers contain potassium ...
Common name Chemical name (Formula) Potash fertilizer: Up to the early 20th century:potassium carbonate (K 2 CO 3). Beginning from the late 19th century: one or more of potassium chloride (KCl), potassium sulfate (K 2 SO 4) or potassium nitrate (KNO 3).
With further heating, potassium perchlorate decomposes to potassium chloride and oxygen: KClO 4 → KCl + 2 O 2. The safe performance of this reaction requires very pure reagents and careful temperature control. Molten potassium chlorate is an extremely powerful oxidizer and spontaneously reacts with many common materials such as sugar.
Potassium perchlorate in crystal form. Potassium perchlorate is prepared industrially by treating an aqueous solution of sodium perchlorate with potassium chloride.This single precipitation reaction exploits the low solubility of KClO 4, which is about 1/100 as much as the solubility of NaClO 4 (209.6 g/100 mL at 25 °C).
Humans have processed common salt (sodium chloride) for over 8000 years, using it first as a food seasoning and preservative, and now also in manufacturing, agriculture, water conditioning, for de-icing roads, and many other uses. [83] Many salts are so widely used in society that they go by common names unrelated to their chemical identity.
Potassium chlorite is a colorless hygroscopic crystal that deliquesces in the air. It decomposes upon heating into potassium chloride and oxygen, emitting light. KClO 2 → KCl + O 2. Potassium chlorite forms orthorhombic cmcm crystals and has been reported to decompose within hours at room temperature. [1] [2] It is an oxidizing agent.
