Preparation

Potassium selenate is produced by the reaction of selenium trioxide and potassium hydroxide.

SeO3 + 2 KOH → K2SeO4 + H2O

Alternatively, it can be made by treating selenous acid with potassium hydroxide, followed by oxidation of the resulting potassium selenite with bromine water.[3]

H2SeO3 + 2 KOH → K2SeO3 + 2 H2O
K2SeO3 + 2 KOH + Br2 → K2SeO4 + 2 KBr + H2O

Uses

Potassium selenate can be used to produce selenium trioxide.[4] It can also use to treat selenium deficiency in livestock.[5]
