Statement-1: In the coagulation of negatively charged arsenic sulphide sol, the coagulating power decreases in the order, Al^3gtBa^(2+)gtNa^+ Statement-2 : Generally greater the valence of coagulating ion, the greater is its power of coagulation.

Assertion : In the coagulation of a negative sol the flocculating power is in the order : Al^(3+) gt Ba^(2+) gt Na^(+) Reason : Greater the valence of the flocculating ion added, greater is its power to cause precipitation.

Greater the flocculation value of an electrolyte, greater is its coagulating power.
