A student says all bases dissolve in water. Which statement is the correct correction?

Answer and explanation

Correct answer: All bases do not dissolve in water and soluble bases are called alkalis

The governing concept is the distinction between a base and an alkali. A base is a substance that can neutralise an acid, but some bases are insoluble in water. Only a base that dissolves in water is called an alkali; for example, sodium hydroxide is an alkali. Therefore option B correctly corrects the student. The other statements confuse solubility, acidity, or neutralisation.
