Ionization gives a concept about the formation of ions while dissociation discusses the formation of small constituents from larger compounds. Ionization occurs when a molecule or an atom loses or gains an electron or few electrons ; on the other hand, dissociation occurs with the addition of energy in the form of heat and the addition of solvent.
In the end, ionization always forms ions; on the contrary, in the end, the product of dissociation, it always produces atoms, ions, or molecules that are smaller than the initial material. Ionization includes the creation of charges across the contributing species; conversely, dissociation occurs because of the weak bond between species. Ionization includes polar covalent compounds or metals as its initial compounds while dissociation contains ionic compounds.
Ionization is an irreversible process, whereas dissociation is a reversible process. Ionization contains covalent bonds between atoms; conversely, dissociation involves ionic bonds in their compounds. Ionization is the method by which a molecule or an atom acquires a positive or a negative charge by losing or gaining of electrons often in combination with other chemical changes, and the resulting electrically charged molecule or an atom is called ion.
Ionization generally results from the loss of an electron after collisions with other atoms, after collisions with subatomic particles, molecules, and ions. Ionization takes place through emitting radiation by the internal transformation process in which an excited nucleus transmits its energy to one of the inner-shell electrons causing it to be emitted. Ionization is an irreversible process. The major causes for dissociation are the addition of solvent and the addition of energy in the form of heat.
When an ionic compound is dissolved in water, it is dissociated into its ionic constituents. Figure 2: Acetylsalicylic Acid Dissociation. Dissociation constant is the ratio between the concentrations of products and the reactant concentration after dissociation. This has a constant value if the temperature is constant. Let us consider an example, water. Dissociation: Dissociation is the breakdown of a substance into smaller particles such as atoms, ions or molecules.

Dissociation: Dissociation forms atoms, ions or molecules that are smaller than the starting material.
