Question:

Why do HCl, HNO3, etc., show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character?

Answer:

HCl or HNO3  shows acidic character on aqueous solution because hydrogen ions  dissociation always occurs in the presence of water. Hydrogen ions (H+) when combined  with H2O to form hydronium ions (H3O+).

The reaction is as follows:

HCL(aq)  →  H+ + CL-

H+ + H2O → H3O+

Whereas aqueous solutions of glucose and alcohol contain hydrogen, these cannot dissociate in water to form hydrogen ions. Therefore they do not show acidic character.
