|potassium chloride |
A white crystalline solid or powder used widely in fertilizers and in the preparation of most potassium compounds. It occurs naturally as the mineral sylvite. A unique property of potassium chloride is that it is more soluble in hot water, but less soluble in cold water, than sodium chloride is. Chemical formula: KCl.
