Vedclass · Answer

(D) According to the Hardy-Schulze rule,the coagulating power of an ion is directly proportional to its valency. Greater the valency of the flocculating ion,the greater is its coagulating power. Coagulating power is inversely proportional to the coagulation value. Therefore,the ion with the highest valency will have the minimum coagulation value. Comparing the valencies: $Cl^{-}$ $(1)$,$SO_4^{2-}$ $(2)$,$PO_4^{3-}$ $(3)$,$[Fe(CN)_6]^{4-}$ $(4)$. The ion $[Fe(CN)_6]^{4-}$ has the highest valency of $4$,hence it has the minimum coagulation value.
