From Wikidoc - Reading time: 1 min
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.
