Question

Predict the products of each of these reactions and write balanced complete ionic and net ionic equations for each. If no reaction occurs, write NO REACTION .

HClO₄(aq) + Ba(OH)₂(aq) →

Express your answer as a chemical equation. Identify all of the phases in your answer. Enter no reaction if no precipitate is formed.

Step 1. Write the overall balanced reactionReactants:• HClO4(aq) → aqueous → will break up into its ions▪ H →  Group 1A → +1 charge → H+▪ ClO4- → polyatomic anion[readmore]• Ba(OH)2(aq) → aqueous → will break up into its ions▪ Ba → Group 2A → +2 charge → Ba2+▪ OH- → polyatomic anionReaction:*criss cross the charges of the cation and anion and that would be the subscript of each ionProducts:• H+ + OH- → H2O(l)• Ba2+ + ClO4- → Ba(ClO4)2▪ Perchlorates (ClO4-) are soluble → Ba(ClO4)2 → soluble → aqueousOverall Balanced Reaction:2 HClO4(aq) + Ba(OH)2(aq) → Ba(ClO4)2(aq) + 2 H2O(l)Step 2: Write the total or full ionic equation2 HClO4(aq) + Ba(OH)2(aq) → Ba(ClO4)2(aq) + 2 H2O(l)▪ 2 HClO4(aq) → 2 H+(aq) + 2 ClO4-▪ Ba(OH)2(aq) → Ba2+(aq) + 2 OH-(aq)▪ Ba(ClO4)2(aq) → Ba2+(aq) + 2 ClO4-(aq)Total Ionic Equation:2 H+(aq)+ 2ClO4- + Ba2+(aq) + 2OH-(aq)→ Ba2+(aq) + 2ClO4-(aq) + 2H2O(l)Step 3. Net ionic equation:2H+(aq) + 2ClO4- + Ba2+(aq) + 2OH-(aq)→ Ba2+(aq) + 2ClO4-(aq) + 2H2O(l)2 H+(aq) + 2 OH-(aq) → 2 H2O(l)
