(a) What is an alkali?

All bases do not dissolve in water. An alkali is a base that dissolves in water. Hence, soluble bases are known as alkali. Eg : NaOH, KOH

(b) HCl and HNO3 furnish H+(aq) ions in water and hence show acidic character.

Alcohol and glucose being covalent compound can't furnish H+(aq) ions in water and hence do not show acidic character.

NOTE : H+ ions are responsible for the acidic properties in any acids. Hence, no dry acids can exhibit its properties as an acid because in dry state H+ ions are not produced. Alcohols and glucose does not produce H+ ions, not even in water. Hence, they do not show acidic character.

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
