Why are all bases not alkalis?

Answer and explanation

Correct answer: Because all bases do not dissolve in water

An alkali is not every kind of base; it is specifically a base that dissolves in water and forms an alkaline solution. Some bases, such as copper(II) oxide, are insoluble or only very slightly soluble in water, so they are bases but not alkalis. Bases can react with acids to form salt and water, and they do contain or produce ions. Therefore option A is correct.
