Question

Why do hcl hno3 extra show acidic character in aqua solution while solution of compound like alcohol and glucose do not show acidic character?

Answer 1

Ans: HCl and HNO3 are strong acids (polar in nature) thus releases H+ ions when dissolved in aqueous solutions where as glucose and alcohol molecules are not acids (and non polar in nature) so, they cannot release H+ ions in aqueous solutions. Alcohols partially release H+ ions in aqueous solutions, so they are considered as weak acids.

Answer 2

The acidic character of a substance is due to the presence of hydrogen ions [H* (aq) ions] in its solution (water solution). HCl and HNO3 show acidic properties because they produce hydrogen ions when dissolved in water. The solutions of compounds like alcohol and glucose do not show acidic character because they do not ionise (or dissociate) in water to produce hydrogen ions. aqueous
