Potassium dihydrogen phosphate (KH2PO4) and sodium nitrate (NaNO2)
Molecular equation:
KH₂PO₄ (aq) + 3NaNO₂(aq) → Na₃PO₄(s) + KNO₂(aq) + 2HNO₂ (aq)
The net ionic equation is:
3Na⁺(aq) + PO₄⁻(aq) → Na₃PO₄(s)
The rest of the ions are spectator ions and tend to cancel out on both sides of the reaction.
