what is the net ionic equation

Question

For the chemical reaction

2HBr(aq)+Ba(OH)2(aq)⟶2H2O(l)+BaBr2(aq)2HBr(aq)+Ba(OH)2⁢(aq)⟶2⁢H2O(l)+BaBr2⁢(aq)

write the net ionic equation, including the phases.

Answer 1

Because H2O(l) is formed along with an aqueous (aq) species, the net ionic equation is simply the formation of the H2O:

2H⁺(aq) + 2OH^-(aq) ==> 2H₂O(l) .. net ionic equation

If you want to see the details of this, write the total ionic equation and then cancel the spectator ions:

2H⁺(aq) + 2Br^-(aq) + Ba²⁺(aq) + 2OH^-(aq) ==> 2H₂O(l) + Ba²⁺(aq) + 2Br^-(aq) .. total ionic equation

2H⁺(aq) + 2OH^-(aq) ==> 2H₂O(l) .. net ionic equation
