WRITING IONIC AND NET IONIC EQUATIONS FOR AN ACID–BASE REACTION

Write both an ionic equation and a net ionic equation for the neutralization reaction of aqueous HBr and aqueous $Ba(OH)_{2}$ .

STRATEGY
Hydrogen bromide is a strong acid whose aqueous solution contains $H^{+}$ ions and $Br^{-}$ ions. Barium hydroxide is a strong base whose aqueous solution contains $Ba^{2+}$ and $OH^{-}$ ions. Thus, we have a mixture of four different ions on the reactant side. Write the neutralization reaction as an ionic equation, and then cancel spectator ions to give the net ionic equation.
