Final answer:
When sodium carbonate is added to a mixture of the reaction and water, it dissociates into its ions, sodium and carbonate. The equation for this reaction is Na2CO3 (aq) + H2O (l) -> 2Na+ (aq) + CO3-2 (aq).
Step-by-step explanation:
The equation for the reaction that occurs when sodium carbonate is added to a mixture of the reaction and water is:
Na2CO3 (aq) + H2O (l) -> 2Na+ (aq) + CO3-2 (aq)
In this reaction, sodium carbonate (Na2CO3) dissociates into its constituent ions, Na+ and CO3-2, when it comes in contact with water (H2O). The complete ionic equation shows the dissociation of the compound into its individual ions.
