Which statement shows that all bases are not soluble in water?

Answer and explanation

Correct answer: Base is a broader class while water-soluble bases are called alkalis

A base is a substance that can neutralise an acid, but it need not dissolve in water. An alkali is specifically a base that dissolves in water and produces hydroxide ions in solution. Therefore, alkalis form a subset of bases: every alkali is a base, but every base is not necessarily an alkali. The other choices describe incorrect universal claims or reverse the behaviour of bases.
