The degree of dissociation \alpha of a weak electrolyte can be determined by measuring the electrical conductivity of the solution. This is because the electrical conductivity of a solution depends on the concentration of ions present in the solution. A weak electrolyte only partially dissociates, which means that there are fewer ions in solution compared to a strong electrolyte. Therefore, the electrical conductivity of a solution containing a weak electrolyte will be lower than that of a solution containing a strong electrolyte. By measuring the electrical conductivity of the solution and comparing it with the electrical conductivity of a solution of known concentration of the same electrolyte, the degree of dissociation can be determined.
