I understand that adding nitric acid to barium phosphate dissolves the precipitate formed from a sodium phosphate solution that is mixed with barium chloride. However I am having trouble balancing the equation. According to the phosphate reaction guidelines, no gas evolves. Is that incorrect?

What I have so far:

Ba₃(PO₄)₂ + H⁺   3 Ba²⁺ + 2PO₄^3- + H₂O

I realize this isn't balanced but I'm having trouble understanding this reaction.

Thank you!

EDIT: Just tried to do some more research and came up with this equation:

Ba₃(PO₄)₂ + 6HNO₃  3Ba(NO₃)₂ + 2H₃PO₄

Can someone confirm that this is correct?

More or less this will happen.

What about BaHPO₄. Check the solubility.
