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.
HCl is a strong acid. A strong acid is defined as an acid that dissociates the ions when it is mixed with water. If the ions do not dissociate when mixed with water, it is considered a weak acid. Continue Reading.
