Solution. 1  The ions from KCl derive from a strong acid (HCl) and a strong base (KOH). 2  Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt.3  Although the K ion derives from a strong base (KOH), the NO 2 ion derives from a weak acid (HNO 2). Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt. 2  Although the K ion derives from a strong base (KOH), the NO 2 ion derives from a weak acid (HNO 2). 3  Therefore the solution will be basic, and KNO 2 is a basic salt.
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.
