Vedclass · Accepted Answer

In the flocculation of a positive sol,flocculating power is in the order,$Cl^{-} > SO_{4}^{2-} > PO_{4}^{3-} > [Fe(CN)_{6}]^{4-}$

Vedclass · Answer

(B) According to the Hardy-Schulze rule,the flocculating power of an ion increases with the increase in the magnitude of the charge on the ion.For a positive sol,the coagulating ions must be negative.The correct order of flocculating power for a positive sol is $[Fe(CN)_{6}]^{4-} > PO_{4}^{3-} > SO_{4}^{2-} > Cl^{-}$.Therefore,the statement in option $B$ is incorrect as it presents the reverse order.
