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.It is a highly corrosive, strong mineral acid with many industrial uses.ydrochloric acid is produced in solutions up to 38% HCl (concentrated grade). Higher concentrations up to just over 40% are chemically possible, but the evaporation rate is then so high that storage and handling need extra precautions, such as pressure and low temperature.
