All bases are not soluble in water. Which statement is most correct?
Answer and explanation
Correct answer: A water-soluble base forms an alkaline solution
A base is a substance that can neutralise an acid, but not every base dissolves appreciably in water. A base that dissolves in water produces hydroxide ions and gives an alkaline solution; such a soluble base is called an alkali. Therefore option A is the most correct. Option B confuses acids with bases, option C contradicts the existence of soluble bases, and option D ignores the colour change of indicators.
