Answer : The net ionic equation will be:

Explanation :
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.
Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The balanced molecular equation will be,

The complete ionic equation in separated aqueous solution will be,

In this equation the species,
are the spectator ions.
By removing the spectator ions , we get the net ionic equation.
The net ionic equation will be:
