Difference between an alkali and a base:
| Alkali | Base |
|---|---|
| An alkali is a compound which when dissolved in water yields hydroxyl ions [OH-] as the only negatively charged ions. | A base is either a metallic oxide or a metallic hydroxide or ammonium hydroxide which reacts with hydronium ions of an acid to form salt and water only. |
| Alkalis are soluble in water | Bases may be or may not be soluble in water. |
| All alkalis are bases | All bases are not alkalis. |
