Question

What is the formula for barium phosphate?

Answer 1

Nominally `Ba_3(PO_4)_2`......

Explanation:

The salt derives barium ion, `Ba^(2+)`, and phosphate ion, `PO_4^(3-)`. A neutral salt is formed from the formulation `Ba_3(PO_4)_2`.

Most of the time, we probably deal with the bisphosphate, `BaHPO_4`.
