selenic acid has a powerful attraction for water, and evolves much heat when mixed with it.
Sulphurous acid has no action on selenic acid, but instantly decomposes the selenious acid.
selenic acid may be obtained in solution by deflagrating selenium or a selenite with potassic nitrate.
When heated in a tube, oxide of selenium of a carmine red rises along with selenic acid, white and deliquescent.
