Among the following, the ion which will be more effective for flocculation of $Fe(OH)_{3}$ sol is:

Statement $I:$ For colloidal particles,the values of colligative properties are of small order as compared to values shown by true solutions at the same concentration.
Statement $II:$ For colloidal particles,the potential difference between the fixed layer and the diffused layer of opposite charges is called the electrokinetic potential or zeta potential.
In the light of the above statements,choose the correct answer from the options given below.
