A '''basicBasic oxideoxides''' isare an oxide[[Oxide|oxides]] that showsshow [[Base (chemistry)|basic]] properties in opposition to [[acidicAcidic oxide|acidic oxides]]s and that either

*reacts with [[water]] to form a [[base (chemistry)|base]]; or

*reacts with an [[acid]] to form a [[salt (chemistry)|salt]] and water.

Basic oxidesThey are oxidesusually mostlyformed ofby reacting oxygen with [[metals]], especially [[alkali metals|alkali]] and [[alkaline earth metals|alkaline earth]] metals. Whereas non-metals usually form [[Acidic oxide|acidic oxides]].

It is formed by reacting oxygen with metals.

Examples include:

*[[Sodium oxide]], which reacts with water to produce [[sodium hydroxide]]

*[[Magnesium oxide]], which reacts with [[hydrochloric acid]] to form [[magnesium chloride]]

*[[Copper(II) oxide]], which reacts with [[nitric acid]] to form [[copper nitrate]]

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

Metals form basic oxides and non-metals form acidic oxides.
