Why can BaSO4 and Ca3 (PO4) 2 be distinguished from each other by concentrated nitric acid?

BaSO4. Barium sulfate is insoluble in alkalis and most acids, but soluble in chlorine water, hydrobromic and hydroiodic acids. That is, barium sulfate does not interact with nitric acid. Ca3 (PO4) 2. Calcium phosphate interacts with nitric acid. We write down the reaction equation. Ca3 (PO4) 2 + 6HNO3 -> 2H3PO4 + 3Ca (NO3) 2. When calcium phosphate interacts with nitric acid, the result is phosphoric acid and calcium nitrate.
