H3PO4(aq)+Ba(OH)2(aq) what does this equation yield and correctly balance Soluti

Question

Explanation / Answer

The balanced equation of this reaction is: Ba(OH)2 (aq) + H3PO4 (aq) -> 2H2O (l) + BaHPO4 (aq) you break those compounds down to ions IF it is considered soluble (based on solubility table), meaning they exist only as ions. if it is weak acid, weak base, or molecular, you keep it the same. For the ionic equation: Ba2+ (aq) + 2 OH- (aq) + H3PO4 (aq) -> 2 H2O (l) + Ba2+ (aq) + HPO4 2- (aq) Then cancel both side that has something in commonwith the identical physical state, only Ba2+ (aq) is common. So, the net ionic equation is: 2 OH- (aq) + H3PO4 (aq) -> 2 H2O (l) + HPO4 2- (aq) Calcium carbonate is considered insoluble. So, you don't break it down into ions. The net ionic equation is: 2 H+(aq) + CaCO3(s) -> Ca2+(aq) + H2O(l) + CO2(g)
