NH4Cl and Na2CO3 total ionic equation and net ionic equation

The total ionic equation is:

2NH₄⁺ (aq) + 2Cl⁻ (aq) + 2Na⁺ (aq) + CO₃⁻² (aq) → (NH₄) ₂CO₃ (s) + 2Na⁺ (aq) + 2Cl⁻ (aq)

The net ionic equation is: 2NH₄⁺ (aq) + CO₃⁻² (aq) → (NH₄) ₂CO₃ (s)

Explanation:

To determine the net ionic equation and the total ionic equation we may know that a change of state is produced in this reaction.

The reactants are: NH₄Cl and Na₂CO₃

We dissociate them:

NH₄Cl (aq) → NH₄⁺ (aq) + Cl⁻ (aq)

Na₂CO₃ (aq) → 2Na⁺ (aq) + CO₃⁻² (aq)

The ammonium carbonate is a solid salt, while the sodium chloride is a soluble one. So we have produced a solid, that's why there is a chagen of state.

The total ionic equation is:

2NH₄⁺ (aq) + 2Cl⁻ (aq) + 2Na⁺ (aq) + CO₃⁻² (aq) → (NH₄) ₂CO₃ (s) + 2Na⁺ (aq) + Cl⁻ (aq)

The ions that are repeated must be removed from the equation (they are called spectators ions, because they do not participate in the reaction)

The net ionic equation is: 2NH₄⁺ (aq) + CO₃⁻² (aq) → (NH₄) ₂CO₃ (s)
