Some have third anions.NamingA selenate selenite compound may also be called a selenite selenate.ProductionOne way to produce a selenate selenite compound is to evaporate a water solution of selenate and selenite compounds.PropertiesOn heating, selenate selenites lose SeO2 and O2 and yield selenites, and ultimately metal oxides.RelatedRelated to these are the sulfate sulfites and tellurate tellurites. They can be classed as mixed valent compounds.
