Answer:
Co2+ + CO32- → CoCO3
Step-by-step explanation:
The molecular equation for the reaction between cobalt (II) iodide and sodium carbonate is:
CoI2 + Na2CO3 → CoCO3 + 2NaI
To write the net ionic equation, we need to eliminate the spectator ions, which are the ions that appear on both the reactant and product side of the equation and do not participate in the reaction. In this case, the spectator ions are Na+ and I-.
The net ionic equation for this reaction is:
Co2+ + CO32- → CoCO3
Therefore, the net ionic equation for the reaction between cobalt (II) iodide and sodium carbonate is:
Co2+ + CO32- → CoCO3
