Which is the correct net ionic equation for the reaction between HC₂O₄^- and HPO₄^2-? (Note:
H₂C₂O₄ is a stronger acid than H₂PO₄^-.)

Question

Which is the correct net ionic equation for the reaction between HC₂O₄^- and HPO₄^2-? (Note: H₂C₂O₄ is a stronger acid than H₂PO₄^-.)

Quizplus · Accepted Answer

The net ionic equation only includes the species that participate in the chemical reaction, which are the ones that underwent a chemical change. The stronger acid, HC₂C₂O₄, donated a proton to the weaker base, H₂PO₄^-, forming the conjugate base of the stronger acid (C₂O₄^2-) and the conjugate acid of the weaker base (H₂PO₄^-). The remaining ions (HPO₄^2-) do not undergo a chemical change and are called spectator ions. Choice C is the only option that correctly represents the net ionic equation for this reaction.
