You have 2 chemicals A (solid), but you do not know the exact composition od either one of them. You do know that all together, there is SOME combination of sodium, barium, chloride and phosphate (PO4^-3) present. You disolve both chemicals in water. then you mix A and B together. You observe there is a cloudy precipitate forms in a clear colorless solution (mostly water?)
Predict and write 2 possible BALANCED equations for the 2 most likely reactions that could have occured.
I don't know how to start. What do i do. Please help.
