Vedclass · Answer

(A) According to the Hardy-Schulze rule,the coagulating power of an ion is directly proportional to the magnitude of its charge.For the precipitation of a positive sol,the anion with the highest negative charge will have the maximum coagulating power.Comparing the charges: $\left[Fe(CN)_6\right]^{4-}$ has a charge of $-4$,$PO_4^{3-}$ has $-3$,$SO_4^{2-}$ has $-2$,and $Cl^{-}$ has $-1$.Therefore,$\left[Fe(CN)_6\right]^{4-}$ has the maximum coagulating power.

Which of the following anions has the maximum coagulating power for the precipitation of a positive sol?
