3. If the distance between two ions of the same charge is increased, what will happen to the energy of interaction between the ions? Why?

The electrostatic attraction energy between ions of opposite charge is directly proportional to the charge on each ion (Q 1 and Q 2 in Equation 4.1. 1). Thus, more energy is released as the charge on the ions increases(assuming the internuclear distance does not increase substantially).
