Assertion(A) : For coagulation of positively charged sols, [Fe(CN)6]4– ion has higher coagulating power than that of \(\mathrm{PO}_{4}^{3-}\), \(\mathrm{SO}_{4}^{2-}\), Cl–.
Reason(R) : Because according to Hardy Schulze rule, higher is the valency of ions for the oppositely charged sol particles, better will be the precipitation.
