<h3>What is dissociation of compounds?</h3>
Dissociation of compound is the process by which compounds degraded into smaller unit which can also recombine to form larger one in another condition.
When ionic compounds dissociate in water, the water molecules separate the ionic crystal. This is because of the attraction between the positive and negative ions in the crystal.
Therefore, The following compounds dissociate in water.
Ba(NO3)2
CaSO4
Mg3(PO4)2
