Potassium selenate, K
2SeO
4, is an odorless, white solid that forms as the
potassium
salt of
selenic acid.
Potassium selenate is produced by the reaction of selenium trioxide and potassium hydroxide.
Alternatively, it can be made by treating selenous acid with potassium hydroxide, followed by oxidation of the resulting potassium selenite with bromine water. [3]
Potassium selenate can be used to produce selenium trioxide. [4] It can also use to treat selenium deficiency in livestock. [5]
