Vedclass · Answer

(D) According to the Hardy-Schulze rule, the coagulation power of an electrolyte depends on the valency of the ion carrying a charge opposite to that of the colloidal particles.
For a positive sol, the effective coagulating ions are anions.
Coagulation power $\propto$ Valency of the effective ion.
Comparing the valencies of the given anions:
$NO_3^-$ (valency = $1$)
$SO_4^{2-}$ (valency = $2$)
$PO_4^{3-}$ (valency = $3$)
$[Fe(CN)_6]^{4-}$ (valency = $4$)
Since $[Fe(CN)_6]^{4-}$ has the highest valency, it has the maximum coagulation power.

For a positive sol, which of the following has the maximum coagulation power?
