The coagulationof 200 mL of a positive sol took place when 0.73 g HCl was added to it without changing the volume much. The flocculation value of HCl for the colloid is :

Which of the following ions has the maximum flocculation value towards coagulation of a positive sol?

Read the given passage and answer the question that follow: Colloidal particles always carry an electric charge which may be either positive or negative. For example, when AgNO_3 solution is added to KI solution, a negatively charged colloidal sol is obtained. The presence of equal and similar charges on colloidal particles provide stability to the colloidal sol and if, somehow, charge is removed. coagulation of sol occurs. Lyophobic sols are readily coagulated as compared to lyophilic sols. Out of KI or K_2SO_4 , which electrolyte is better in the coagulation of positive sol?
