Is Magnesium hydroxide alkali or salt

Magnesium oxide (MgO) is neither a salt nor an alkali. Not all substances are either acids, bases, or salts, there are other categories.


Salt is a type of compound that can produce metal ions (or ammonium ions) and acid ions during ionization;


Bases are compounds in which all anions generated during ionization are Hydroxide ion ions.


In other words, acid radical should be found in salt and Hydroxide ion radical should be found in alkali,


Magnesium oxide is a metal oxide that belongs to covalent compounds and is not ionized, let alone acid radicals.
