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 1

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+).


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.

Hope this will help you...

Answer 2

Dear Student,

◆ Answer with explanation -

• Acids are chemical substances that dissociate to give H+ ion in aqueous solution.
• As HCl & HNO3 have H+ ions to release, they show acidic characters in aqueous solutions.
• On the other hand, solutions of alcohol and glucose doesn't have H+ ions to give, hence It can't show acidic character.

Thanks dear. Hope this helps you...
