Question
Why do $HCl _2, HNO _3$, etc., show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character?
✓
Answer
When HCl or $HNO _3$ are mixed with water then they dissolve in water to form $H ^{+}$or $H _3 O ^{+}$ions which shows their acidic character.
For example just see the following reactions:
$HCl_{(aq)} \rightarrow H^{+}+Cl^{-}$
$H^{+}+H_2 O \rightarrow H_3 O^{+}$
When alcohols and glucose are mixed with water then they do not dissolve to form ions. Hence they do not show acidic character.
