What is Oxide?
A binary compound of oxygen with another element. Metal oxides are generally basic and react with acids; non-metal oxides are generally acidic and react with bases. Amphoteric oxides (e.g., Al₂O₃) react with both acids and bases.

A binary compound of oxygen with another element. Metal oxides are generally basic and react with acids; non-metal oxides are generally acidic and react with bases. Amphoteric oxides (e.g., Al₂O₃) react with both acids and bases.
Oxides are used in: metallurgy (iron from Fe₂O₃ in blast furnace), cement (CaO from CaCO₃ calcination), ceramics (Al₂O₃, MgO as refractories), pigments (Fe₂O₃ red/yellow, TiO₂ white), acid anhydrides (SO₃ + H₂O → H₂SO₄), semiconductor films (SiO₂ gate insulator, ZnO, TiO₂ as photocatalysts), and in …
Basic metal oxides (CaO, Na₂O) react exothermically with water forming caustic hydroxides — severe burn hazard. Acidic oxides (SO₂, NO₂, Cl₂O) are toxic gases. Heavy metal oxides (PbO, As₂O₃, CrO₃) are highly toxic. Handle all oxides with appropriate PPE and consult their SDS.
