What is Selenide?
'''Selenide''' is an [[ion]]. Its chemical formula is Se<sup>2–</sup>. Selenides are similar to [[sulfide]]s. Selenides are [[reducing agent]]s when pure. They are stronger reducing agents than sulfides. Selenide ores are the source of selenium. Selenides are normally mixed with sulfides. The selenide ion is unstable except in very [[base (chemistry)|basic]] conditions. Normally [[hydroselenide]] is made, which is HSe<sup>-</sup>. In [[acid]]ic conditions, [[hydrogen selenide]] gas is made. ==Related pages== *[[Selenite]] *[[Selenate]] [[Category:Selenium compounds]] [[Category:Ions]]
