Selenate

Selenate

Selenate sind die Salze und Ester der Selensäure H2SeO4. Das Selenat-Anion hat die Formel SeO42−.

Selenate ähneln den Sulfaten stark in ihren chemischen Eigenschaften. Anders als Sulfate sind Selenate gute Oxidationsmittel; dabei werden sie zu Seleniten bzw. Selen reduziert. In sehr saueren Umgebungen bilden sich in Analogie zu den Sulfaten Hydrogenselenat-Ionen, HSeO4−.
