Silver selenite is an inorganic compound of formula Ag2SeO3.
Production
Silver selenite is formed during the recovery of selenium from
copper 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:
Another method is the reaction between selenium and silver nitrate:
- 3 Se + 6 AgNO3 + 3 H2O → 2 Ag2Se + Ag2SeO3 + 6 HNO3
