(a)
Interpretation:
Overall equation, complete ionic equation, and the net ionic equation for the given reaction has to be written.
Concept Introduction:
Reaction between the acid and base is known as a neutralization reaction. The product formed in neutralization reaction is salt and water. The net reaction that takes place between the acid and base solutions is that the formation of water from hydrogen ions and hydroxide ions. Neutralization reaction is the one that takes place between a strong acid and a metal hydroxide.
Complete ionic equation is the one that shows all the species that is present in the
Net ionic equation is the one that is obtained from the complete ionic equation by cancelling out the spectator ions.

Explanation of Solution
Overall equation:
The given incomplete equation is written as follows;
Arsenic acid is a weak triprotic acid. Hence, it is kept in the molecular form itself. The product formed in the reaction is water and trisodium arsenate. The overall equation can be given as shown below;
Complete ionic equation:
The complete ionic equation can be written considering the ionic compounds in aqueous medium to be written into respective ions. Therefore, the complete ionic equation can be given as follows;
Net ionic equation:
The net ionic equation can be obtained from the complete ionic equation by cancelling out the spectator ions on both sides of the equation.
