What are basic oxides?
Basic oxides are usually metallic. Those of group 1 and 2 react with water to form an hydroxide.

What are acidic oxide?
Most non-metal oxides are non-acidic. They react with alkalis to give a salt and water, and also react with bases.
11 of 13
Which oxides are neutral?
Nitrogen(ii) Oxide and Nitrogen(i) oxide
12 of 13
Which oxides are amphoteric?
Those that have both acidic and basic properties. Examples are zinc and aluminium oxides
