Ionic Equilibrium Equilibrium established between the ions and the undissociated electrolyte in a solution is called the ionic equilibrium. In other words, Ionic equilibrium is the study of solutions of electrolyte. Electrolyte:  Substances which furnish ions in aqueous solution or in fused state is called the electrolytes. These substances conduct electricity in their aqueous solutions or in their fused state. Degree of dissociation (α):  The number of molecules dissociated out of total number of molecules originally taken is called the degree of dissociation. Mathematically, It is expressed in percentage or as fraction or decimals. If 40 molecules are dissociated out of 100 molecules than the degree of dissociation is expressed as 40% or 0.4. Strong Electrolytes:  These substances dissociate almost completely into ions in aqueous solutions and hence are good conductor of electricity. Ex: KCl, NaCl, KOH, NaOH etc. Weak   Electrolytes:  These substan...
