Silver selenite explained

Silver selenite is an inorganic compound of formula Ag₂SeO₃.

Production

Silver selenite is formed during the recovery of selenium from copper anode slimes when they are subjected to oxidative roasting, causing some silver selenide to be converted to the selenite. It can also be prepared by a precipitation reaction between silver nitrate and sodium selenite:^[1]

Another method is the reaction between selenium and silver nitrate:^[2]

3 Se + 6 AgNO₃ + 3 H₂O → 2 Ag₂Se + Ag₂SeO₃ + 6 HNO₃
