Lesson Summary. Potassium chloride is an ionic compound and is a salt that naturally occurs as a solid that has a powdery and crystalline appearance. Its chemical formula is KCl: it consists of one potassium (K+) ion and one chlorine (Cl-) ion.Potassium chloride has so many uses in various fields.It is a main component of fertilizer, and in medicine, it treats a condition called hypokalemia, which results when potassium levels in blood are lower than normal.ere, we can see that KCl consists of a positive ion (K+) and a negative ion (Cl-). Salts are ionic compounds consisting of positive and negative ions. Because potassium chloride has ions of opposite charges, potassium chloride is classified as a salt.
