Answer:
2H+ (aq) + 2OH-(aq)→ 2H2O (l)
Explanation:
Step 1: the balanced equation
2HBr(aq) + Ba(OH)2(aq) ⟶ 2H2O(l)+BaBr2(aq)
Step 2: The net ionic equation
The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will , after canceling those spectator ions in both side (Ba^2+ and Br-), look like this:
2H+ (aq) + 2OH-(aq)→ 2H2O (l)
The net ionic equation, including the phases, for the chemical reaction is,
2H⁺(aq) + 2OH⁻(aq) ⟶ 2H₂O(l)
From the question,
We are to write the net ionic equation for the given chemical reaction.
The given balanced chemical equation for the reaction is
2HBr(aq) + Ba(OH)₂(aq) ⟶ 2H₂O(l) + BaBr₂(aq)
Now, we will write the ionic equation for the reaction
The ionic equation for the reaction is
2H⁺(aq) + 2Br⁻(aq) + Ba²⁺(aq) + 2OH⁻(aq) ⟶ 2H₂O(l) + Ba²⁺(aq) + 2Br⁻(aq)
Now, cancel out the spectator ions, Ba²⁺ and Br⁻, to give the net ionic equation.
The net ionic equation is
2H⁺(aq) + 2OH⁻(aq) ⟶ 2H₂O(l)
Hence, the net ionic equation, including the phases, for the chemical reaction is,
2H⁺(aq) + 2OH⁻(aq) ⟶ 2H₂O(l)
