The net ionic equation for this reaction is as follows: 3Ba⁺² + 2PO₄³⁻ → Ba₃(PO₄)₂(s).
What is net ionic equation?
Net ionic equation is the chemical equation that shows only those elements, compounds, and ions that are directly involved in the chemical reaction.
According to this question, 100.0mL of 2.0M sodium phosphate is added to a beaker that has 150.0mL of 2.0M barium chloride. The chemical reaction is as follows;
3BaCl₂ + 2Na₃PO₄ → Ba₃(PO₄)₂ + 6NaCl
In order to write the net ionic equation of a reaction, we simply need to remove the spectator ions. After removing the spectator ions, we are left with the net ionic equation. Spectator ions are ions that is unchanged in an ionic reaction, i.e. that remains in solution and do not take part in the reaction.
In the above reaction, the spectator ions are Na⁺ and Cl⁻, hence, removing this we have;
3Ba⁺² + 2PO₄³⁻ → Ba₃(PO₄)₂(s)
