To write the net ionic equation for the reaction between sodium phosphate (Na3PO4) and zinc sulfate (ZnSO4), we first need to write the balanced molecular equation.
Step 1: Write the balanced molecular equation:
Na3PO4 + ZnSO4 → Zn3(PO4)2 + Na2SO4
In this equation, there are no insoluble products, and all the reactants and products are soluble in water.
Step 2: Write the complete ionic equation:
Na3⁺ + PO4²⁻ + Zn²⁺ + SO4²⁻ → Zn₃(PO4)₂ + 3Na⁺ + 2SO4²⁻
In the complete ionic equation, all soluble compounds are written as separate ions.
Step 3: Write the net ionic equation:
PO4²⁻ + 3Zn²⁺ → Zn₃(PO4)₂
The net ionic equation is obtained by removing the spectator ions, which are the ions that are present on both sides of the equation and do not participate in the reaction. In this case, the spectator ions are Na⁺ and SO4²⁻.
To determine the net ionic equation for the given reaction (Na3PO4 + ZnSO4 = Zn3(PO4)2 + Na2SO4), we need to first write the balanced chemical equation.
Step 1: Write the balanced chemical equation.
Na3PO4 + ZnSO4 → Zn3(PO4)2 + Na2SO4
Step 2: Separate the aqueous compounds into their respective ions.
Na3PO4(aq) → 3Na+(aq) + PO4 3-(aq)
ZnSO4(aq) → Zn2+(aq) + SO4 2-(aq)
Zn3(PO4)2(s) → 3Zn2+(aq) + 2PO4 3-(aq)
Na2SO4(aq) → 2Na+(aq) + SO4 2-(aq)
Step 3: Remove the spectator ions, which are the ions that appear on both sides of the equation.
In this case, the spectator ions are Na+ and SO4 2-.
Step 4: Write the net ionic equation using only the ions involved in the reaction.
The net ionic equation for the given reaction is:
3Na+(aq) + PO4 3-(aq) + Zn2+(aq) → Zn3(PO4)2(s)
So, the net ionic equation is 3Na+ + PO4 3- + Zn2+ → Zn3(PO4)2.
