Silver selenite is an

inorganic compound In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemi ...

of formula Ag₂SeO₃.

Production

Silver selenite is formed during the recovery of selenium from

copper Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish ...

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 Silver nitrate is an inorganic compound with chemical formula . It is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called ''lunar caustic ...

and

sodium selenite Sodium selenite is the inorganic compound with the formula Na2SeO3. This salt is a colourless solid. The pentahydrate Na2SeO3(H2O)5 is the most common water-soluble selenium compound. Synthesis and fundamental reactions Sodium selenite usually i ...

: Another method is the reaction between selenium and silver nitrate: :3 Se + 6 AgNO₃ + 3 H₂O → 2 Ag₂Se + Ag₂SeO₃ + 6 HNO₃
