Ionization and Degree of Ionization

When a electrolyte is dissolved in a solution, it splits into negatively and positively charged ions. This phenomenon is called ionization. For example when NaCl is introduced to water or any solvent, it splits into positively charged ions (Na+)negatively charged ions (Cl) . Ionization is very common in case of liquid. The different properties of a chemical compounds can be determined through its ionization property. No compounds are 100% soluble and fully insoluble in solvents. The solubility of a electrolyte is calculated by measuring its degree of ionization.

Degree of ionization: Degree of ionization is defined as the ratio of moles of the electrolyte dissociated into ions to the total number of moles of electrolyte dissolved in the solution. In other words, it is the fraction of moles of electrolyte dissociated into ions.

$$\text{Degree of ionization} (\alpha ) = \frac{\text{Number of moles ionized }}{\text{total number of moles}}$$
