For other uses, see bromide (disambiguation).

A bromide ion is a bromine atom with charge of −1.

Compounds with bromine in formal oxidation state −1 are called bromides. This can include ionic compounds such as caesium bromide or covalent compounds such as sulfur dibromide. One can test for a bromide ion by adding dilute nitric acid (HNO₃), then silver nitrate (AgNO₃). A cream precipitate forms that disappears in concentrated ammonia solution.

[edit] Examples

• hydrogen bromide (HBr)
• sodium bromide (NaBr)
• carbon tetrabromide (CBr₄)
• sulfur dibromide (SBr₂)
