Multiple Choice

Which equation shown below represents the total ionic equation for the reaction between aqueous solutions of (NH₄) ₃PO₄ and CaCl₂?

• A) 6 NH₃ (g) + 6 H⁺ (aq) + 2 PO₄^{3 -} (aq) + 3 Ca²⁺ (aq) + 3 Cl₂^{2 -} (aq)→ 3 Ca²⁺ (aq) + 2 PO₄^{3 -} (aq) + 3 (NH₄)₂Cl₂ (s)
• B) 6 N^{3 -} (aq) + 24 H⁺ (aq) + 2 P^{3 -} (aq) + 8 O^{2 -} (aq) + 3 Ca²⁺ (aq) + 6 Cl ^- (aq)→ Ca₃(PO₄)₂ (s) + 6 N^{3 -} (aq) + 24 H⁺ (aq) + 6 Cl ^- (aq)
• C) 3 NH₄⁺ (aq) + PO₄^{3 -} (aq) + Ca²⁺ (aq) + 2 Cl ^- (aq)→ CaPO₄ (s) + 3 NH₄⁺ (aq) + 2 Cl ^- (aq)
• D) 6 NH₄⁺ (aq) + 2 PO₄^{3 -} (aq) + 3 Ca²⁺ (aq) + 6 Cl ^- (aq)→ 3 Ca²⁺ (aq) + 2 PO₄^{3 -} (aq) + 6 NH₄Cl (s)
• E) 6 NH₄⁺ (aq) + 2 PO₄^{3 -} (aq) + 3 Ca²⁺ (aq) + 6 Cl ^- (aq)→ Ca₃(PO₄)₂ (s) + 6 NH₄⁺ (aq) + 6 Cl ^- (aq)
