A net ionic equation for the overall reaction that occurs when aqueous solutions of sodium hydroxide and oxalic acid is :
H₂C₂O₄ + 2OH⁻ ----> C₂O₄²⁻ + 2H₂O
The balance molecular equation is given as :
2NaOH (aq) + H₂C₂O₄ (aq) -----> Na₂C₂O₄ (aq) + 2H₂O (l)
now, the complete ionic equation is given as :
H₂C₂O₄ + 2Na⁺ + 2OH⁻ ----> 2Na⁺ + C₂O₄²⁻ + 2H₂O
cancel out the spectators ion the spectators ions are those which are on both side the reactant side and the product side : the net ionic equation is given as :
H₂C₂O₄ + 2OH⁻ ----> C₂O₄²⁻ + 2H₂O
