Selenide

The selenide ion is Se²⁻.

A selenide is a chemical compound in which selenium serves as an anion with oxidation number of −2, much as sulfur does in a sulfide.

Examples[edit | edit source]

• hydrogen selenide, H₂Se
• sodium selenide, Na₂Se

See category for a list.

Discussion[edit | edit source]

The chemistry of the selenides parallels that of the sulfides.

Similar to sulfide, for an aqueous solution, selenide ion, Se²⁻, is prevalent only in very basic conditions. In neutral conditions, hydrogen selenide ion, HSe⁻, is most common. In acid conditions, hydrogen selenide, H₂Se, is formed.
