Final answer:
The net ionic equation for the reaction between potassium carbonate (K₂CO₃) and aluminum nitrate (Al(NO₃)₃) is 2 Al³⁺(aq) + 3 CO₃²⁻(aq) → Al₂(CO₃)₃(s), which shows the formation of solid aluminum carbonate.
Step-by-step explanation:
To find the net ionic equation for the reaction between potassium carbonate (K₂CO₃) and aluminum nitrate (Al(NO₃)₃), begin by writing the balanced chemical equation:
3 K₂CO₃(aq) + 2 Al(NO₃)₃(aq) → Al₂(CO₃)₃(s) + 6 KNO₃(aq)
Break down the soluble compounds into their respective ions:
6 K⁺(aq) + 3 CO₃²⁻(aq) + 2 Al³⁺(aq) + 6 NO₃⁻(aq) → Al₂(CO₃)₃(s) + 6 K⁺(aq) + 6 NO₃⁻(aq)
Cancel out the spectator ions, which are the ions that appear on both sides of the equation and do not participate in the reaction:
Net ionic equation:
2 Al³⁺(aq) + 3 CO₃²⁻(aq) → Al₂(CO₃)₃(s)
This net ionic equation shows the formation of solid aluminum carbonate from aluminum and carbonate ions. The potassium and nitrate ions are spectator ions and are not included in the net ionic equation as they do not participate in the formation of the precipitate.
