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.
Hydrochloric acid is a clear, colorless, highly pungent solution of hydrogen chloride (H Cl) in water.t was historically called acidum salis, muriatic acid, and spirits of salt because it was produced from rock salt and green vitriol (by Basilius Valentinus in the 15th century) and later from the chemically similar substances common salt and sulfuric acid (by Johann Rudolph Glauber in the 17th century).
