What’s the net ionic equation?

Question

Write the balanced net ionic equation for the reaction between iron(II) percholate and sodium oxalate. Include phases.

Fe(ClO4)2(aq)+ Na2C2O4(aq)——>

Answer 1

Fe(ClO₄)₂(aq)+ Na₂C₂O₄(aq) ===> FeC₂O₄(s) + 2NaClO₄(aq) ... molecular equation

Fe²⁺(aq) + C₂O₄^2-(aq) ===> FeC₂O₄(s) ... net ionic equation (see below)

The way to find the net ionic is to write the complete ionic equation:

Fe²⁺(aq) + 2ClO₄^-(aq) + 2Na⁺(aq) + C₂O₄^2-(aq) ==> FeC₂O₄(s) + 2Na⁺(aq) + 2ClO₄^-(aq)

And now remove spectator ions which are 2Na⁺(aq) and 2ClO₄^-(aq), leaving you with

Fe²⁺(aq) + C₂O₄^2-(aq) ===> FeC₂O₄(s) ... net ionic
