Adiabatic ionization is a form of ionization in which an electron is added or removed to an atom or molecule in its lowest energy state resulting from an ion in its lowest energy state.
Dissociation is a universal process in which molecules split or separate into smaller particles such as ions, atoms, or radicals, generally in a reversible manner because these smaller particles are usually capable of recombining together at given conditions. The major reasons for dissociation are the addition of energy in the form of heat and the addition of solvent.
When an ionic complex is dissolved in water, it dissociates into its ionic elements. Above discussion concludes that ionization is the formation of new charged particles which were absent in the previous compound while dissociation is the separation of charged particles which were already existed in the compound.

Dissociation may occur forming atoms, ions or radicals. 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.
Ionization: Ionization is the formation of ions. Dissociation: Dissociation is the formation of small constituents from larger compounds. Ionization: Ionization occurs when an atom or a molecule gains or loses an electron or few electrons. Dissociation: Dissociation occurs with the addition of solvent and the addition of energy in the form of heat. In this process, electrically neutral atoms become electrically charged particles.
This charge can be either positive or negative. That is dependent on the gain or loss of an electron. If an atom or a molecule loses an electron, it will become positively charged whereas if it gains an electron from the outside, it will become negatively charged.
Ionization process is usually irreversible, which means, if an atom or molecule gains an electron, it does not release that electron back; if an atom loses an electron, it will not take an electron back. That happens when the loss or gain of this electron causes a stable ion, which obeys the octet rule.
Sometimes the term ionization gets confused with dissociation. If an ionic compound such as sodium chloride NaCl is considered, it will form ions when dissolved in water.
Although this forms ions, this is not ionization. Since the solid NaCl is split into its ions or their ionic bonds are broken, it cannot be termed as ionization. Thus, the split of an ionic bond is not an ionization process because an electron has already given to one atom by the other atom and only an electrostatic attraction exists.
Hence, it can be said that compounds having ionic bonds will not take part in ionization. Although ionic compounds cannot undergo ionization, covalent compounds having covalent bonds between atoms can undergo ionization process.
This is because electron sharing occurs in in covalent bonds and ionization of those compounds will produce new charged particles which were absent in the previous compound. But ionization only occurs in polar covalent compounds having atoms with a considerable difference in electronegativity. Otherwise, ionization will not occur due to strong covalent bonding. Ionization also takes place in metals.
There, positively charged metal ions are produced by releasing electrons from metal atoms. Dissociation refers to break or split of a compound into smaller particles. Dissociation process can result in products that are either electrically charged or neutral.
This does not involve the gain or loss of electrons by the atoms. Unlike ionization process, dissociation is the separation of ions which already existed in a compound. Sometimes, dissociation may also produce neutral particles.
