Metal cation ionic solids dissolve in solution exothermically.

Which of the following BEST explains this phenomenon?

A

The hydrogen bonding in the water breaks apart, releasing large amounts of energy that are used to force a breaking of the ionic structure.

B

The free floating electrons in the metal cations provide a large measure of electricity when the ionic solid is broken down in the water.

C

The breaking of the ionic structure, which releases bond energy causing the solution to be exothermic.

D

The attraction of the cations and anions to the dipoles in water, resulting in a release of energy.
