Question

What is then nature of magnesium oxide acidic or basic

Answer 1

A basic oxide is an oxide that shows basic properties in opposition to acidic oxides and that either

reacts with water to form a base; orreacts with an acid to form a salt and water.

Examples include:

Sodium oxide, which reacts with water to produce sodium hydroxideMagnesium oxide, which reacts with hydrochloric acid to form magnesium chlorideCopper(II) oxide, which reacts with nitric acid to form copper nitrate

Basic oxides are oxides mostly of metals, especially alkali and alkaline earth metals.

Answer 2

Depending on its concentration, this will have a pH around 14. As a strong base, sodium oxide also reacts with acids. For example, it would react with dilute hydrochloric acid to produce sodium chloride solution. Magnesium oxide is again a simple basic oxide, because it also contains oxide ions.

BUT MAGNESIUM OXIDE IS NEITHER ACIDIC OR BASIC IT'S JUST A SUPPORTER OF COMBUSTION...
