What is the conclusion that you take about nature of aluminum oxide with help of equation.Give reasons for conclusions?

You can say that Al has a +3 charge and O has a -2 charge and therefore AlO2 has a -1 charge.
The inference you can make this reaction is that Aluminum oxide is a basic oxide, because it forms a salt upon reacting with a base.
(Do keep in mind, however, that Al2O3 is amphoteric. From this reaction, you can only infer its basic nature)
