Selenite (ion)
From Wikipedia, the free encyclopedia
The selenite ion is SeO32−.
A selenite (compound) is a compound that contains this ion.
In slightly acid conditions, we have hydrogen selenite ion, HSeO3−; with more acidic conditions we have selenous acid, H2SeO3.
Most selenite compounds can be formed by heating the relevant oxide with selenium dioxide, e.g., Na2O + SeO2 -> Na2SeO3.
