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

Acids form hydrogen ions [$H^+$ (aq) ions] in its aqueous solution which are responsible for their acidic characters. $HCl \ and \ HNO_3$  form hydrogen ions in aqueous solution hence, they show acidic characters in aqueous solution.
$HCl_{(aq)}\rightarrow H^++Cl^-$
$H^++H_2O\rightarrow H_3O^+$
