Final answer:
Dissociation is the separation of ions that occurs when a solid ionic compound dissolves, whereas dissolution is the process by which a solute dissolves into a solvent and forms a solution.
Step-by-step explanation:
Dissociation is the separation of ions that occurs when a solid ionic compound dissolves.
Dissolution is the process by which a solute dissolves into a solvent and forms a solution.
So, while dissociation specifically refers to the separation of ions in a solid ionic compound, dissolution is a more general process that involves the overall process of a solute dissolving into a solvent.
