प्रश्न
Assertion: Coagulation power of Al3+ is more than Na+.
Reason: Greater the valency of the flocculating ion added, greater is its power to cause precipitation (Hardy Schulze rule).

उत्तर
Assertion and reason both are correct and the reason is correct explanation of assertion.
Explanation:
To Hardy-Schulze law, the greater is the valency of the coagulating ion, the more is the power to coagulate the colloidal solution. Thus, coagulation power of Al3+is greater than that of Na+.
