What is the name of B2 (SeO4) 3

Boron Selenate

Explanation:

The compound contains B^3 + and the selenate anion SeO4^2-.

Selenate (Se (VI)) is quite weakly adsorbed by oxides and clays almost at neutral pH. Hence, oxidation of Se (IV) to Se (VI) enhances selenium mobility and persistence in natural water bodies. High concentrations of selenate can occur in agricultural drainage waters in arid areas. Selenate is further found in irrigation waters across the USA.

Many selenate compounds are known having various counter ions.

This compound is Boron selenate. Molar mass of B2 (SeO4) 3 is 450.4948 g/mol.
