Potassium Chloride

Potassium Chloride KCl is a compound, a combination of 2 elements: Potassium + Chloride. Potassium chloride is a colorless or white, cubic, crystalline compound. It is odorless, stable in air and highly soluble in water. Potassium chloride is soluble in water and alcohol and closely resembles common salt. Potassium chloride occurs pure in nature as the mineral sylvite and is found combined in many minerals and in brines and ocean water. It is produced from sylvinite, a …

…salt can then be purified by recrystallization. However, potassium chloride is available in massive amounts in nature and can simply be recrystallized to recover it. KOH(aq) + HCl(aq) KCl(aq) + H2O(l) While not a normal route of preparation because of the expense, potassium metal reacts vigorously with all the halogens to form potassium halides. So, it burns with chlorine, Cl2, to form potassium (I) chloride, KCl. 2K(s) + Cl2(g) 2KCl(s)
