in this reaction, the ca and the no ions remain in solution and are not part of the reaction. that is, these ions are identical on both the reactant and product side of the chemical equation. because such ions do not participate in the reaction, they are called spectator ions. a "net ionic" equation is the full ionic equation from which the spectator ions have been removed. the net ionic equation of the proceeding reactions is:









































or, in "reduced" balanced form,









































in a neutralization or acid/base reaction, the net ionic equation will usually be:
