Normal salts are formed when all the replaceable hydrogen ions in the acid have been completely replaced by metallic ions. Trioxonitrate(V) acid, HNO\(_3\) has only one replaceable hydrogen ion(monobasic), that can be replaced by a metallic ion or ammonium ion. Thus, it cannot form an acidic nor basis salt or any other type aside normal salt.
