Answer 2

ALUMINIUM OXIDE

Al2O3 is the most acidic among the given oxides.

GETTING TO KNOW MORE ABOUT ALUMINIUM OXIDE:

* Because aluminium oxide comes in a variety of forms, describing its qualities can be difficult. One of these forms is very inert (chemically known as alpha-Al2O3) and is formed at extremely high temperatures.

* The reactions that follow involve the molecule's more reactive forms. Aluminium oxide is an amphoteric substance. It reacts both as a basic and as an acid.

* Aluminum oxide is insoluble in water and does not react in the same way as sodium oxide and magnesium oxide do. The oxide ions are trapped in the solid lattice too tightly to react with the water.

* Aluminum oxide, which includes oxide ions, interacts with hot dilute hydrochloric acid to produce aluminium chloride solution.
