Detailed Solution

The reason why

HCl

HN O_{3}

etc. show acidic characters in aqueous solutions while solutions of compounds like

C_{2} H_{5} OH

and glucose does not show acidic character because there is production of hydrogen ions in acids.
The aqueous solutions of

HCl

and

HN O_{3}

ionise to produce

H^{+}

ions. Due to the production of hydrogen ions in the aqueous solutions, they show an acidic character. But compounds like

C_{2} H_{5} OH

and glucose dissolve in water and dissociate to produce

O H^{-}

ions but not

H^{+}

ions; thus, they don’t have an acidic character. The presence of

O H^{-}

ions in glucose indicate that it is a base.
