Why are spectator ions omitted from an ionic equation?
A
Only the coefficients.
B
- They balance the carbonate ion's 2- charge
- They supply two hydrogen atoms for water
C
They are unchanged during the reaction.
D
The ionic equation for an acid reacting with carbonate ions is CO32−(aq)+2H+(aq)→CO2(g)+H2O(l)\boxed{\text{CO}_3^{2-}\text{(aq)} + 2\text{H}^{+}\text{(aq)} \rightarrow \text{CO}_2\text{(g)} + \text{H}_2\text{O(l)}}CO32−(aq)+2H+(aq)→CO2(g)+H2O(l).
