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.

Assertion (A) Coagulation power of Al^(3+) is more than Na^(+) . Reason (R) Greater the valency of the flocculating ion added, greater is its power to cause precipitation (Hardy-Schulze rule) .

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

In the following question, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as. Assertion (A): Coagulation power of Al^(3+) is more than Na^(+) . Reason (R): Greater the valency of the flocculating ion added, greater is its power to cause precipitation (Hardy-Schulze rule).

The coagulating power of ions, for a negative sol changes in the order

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.

For the coagulation of a negative sol, the species below, that has the highest flocculating power is :

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

The correct order of the flocculating power in the coagulation of a positive sol is
