Copper oxide alkali or base

WebA soluble base is called an alkali if it contains and releases OH − ions quantitatively. Metal oxides, hydroxides, and especially alkoxides are basic, and conjugate bases of weak acids are weak bases. WebBases can be either ionic or covalent compounds. Examples of bases include copper oxide (CuO), zinc oxide (ZnO), and ammonia (NH3). Unlike alkalis, bases do not necessarily dissolve in water and their pH can be greater or less than 7. There are many misconceptions about what an alkali and base is.
