Question

The degree of dissociation of weak electrolyte increases by :

• A. increasing the concentration of weak electrolyte solution
• B. adding a common ion
• C. dissolution in solvent of low dielectric constant
• D. adding more amount of solvent into the solution

Answer 1

The correct option is D adding more amount of solvent into the solution

When more amount of solvent is added to the solution, it helps in dissociating the molecules into ions of a weak electrolyte. Thus, degree of dissociation of weak electrolyte increases upon dilution.
