Vedclass · Answer

(B) According to the Hardy-Schulze rule, the coagulating power of an ion increases with the increase in the magnitude of the charge on the ion used for coagulation.For a positively charged sol, the coagulating power of anions follows the order: $[Fe(CN)_6]^{4-} > PO_4^{3-} > SO_4^{2-} > Cl^-$.Since $[Fe(CN)_6]^{4-}$ has the highest negative charge $(-4)$, it has the greatest coagulating power.

Which of the following anions has the greatest coagulating power for a positively charged sol?
