Multiple Choice

Which equation best represents the net ionic equation for the reaction that occurs when aqueous solutions of potassium phosphate and iron(II) nitrate are mixed?

• A)3Fe²⁺(aq)+ 2PO₄^3-(aq)→ Fe₃(PO₄)₂(s)
• B)2K⁺(aq)+ Fe(NO₃)₂(aq)→ 2KNO₃(aq)+ Fe²⁺(aq)
• C)3Fe²⁺(aq)+ 2PO₄^3-(aq)→ Fe₃(PO₄)₂(aq)
• D)2K₃PO₄(aq)+ 3Fe²⁺(aq)→ Fe₃(PO₄)₂(s)+ (K⁺)₆(aq)
• E)2K₃PO₄(aq)+ 3Fe(NO₃)₂(aq)→ Fe₃(PO₄)₂(s)+ 6KNO₃(aq)
