Explain the difference between a base and an alkali.

Answer

The main difference is that all alkalis are bases, but not all bases are alkalis. An alkali is a specific type of base that dissolves in water to form hydroxide ions, while a base is a more general term that refers to any substance that can accept hydrogen ions or donate a pair of electrons.
