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.
Weak acids dissociate partially, while strong acids dissociate completely in water. One of the most notable strong acids is hydrochloric acid (HCl or hydrogen chloride). Let's discuss HCl and its properties as a strong acid. Chemical Properties of HCl. Hydrochloric acid is a strong acid and is made of hydrogen and chlorine atoms. Hydrogen and chlorine atoms participate in covalent bonding, which means that hydrogen will share a pair of electrons with chlorine.
