Question 1:
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
The dissociation of HCl or HNO3 to form hydrogen ions always occurs in the presence
of water. Hydrogen ions (H+) combine with H2O to form hydronium ions (H3O+).
The reaction is as follows:
HCl(aq) → H+ + Cl−
H+ + H2O → H3O+
Although aqueous solutions of glucose and alcohol contain hydrogen, these cannot
dissociate in water to form hydrogen ions. Hence, they do not show acidic character.
