Vedclass · Answer

(A) Ferric hydroxide sol $(Fe(OH)_3)$ is a positively charged sol. According to the Hardy-Schulze rule,the coagulating power of an electrolyte increases with the increase in the magnitude of the charge on the ion opposite to that of the colloidal particle. Since the sol is positively charged,the coagulating power depends on the negative ion (anion). The valency of the anions in the given options are: $A$: $[Fe(CN)_6]^{4-}$ (valency = $4$) $B$: $C_2O_4^{2-}$ (valency = $2$) $C$: $[Fe(CN)_6]^{3-}$ (valency = $3$) $D$: $F^-$ (valency = $1$) Since the anion with the highest valency $(4)$ has the highest coagulating power,$K_4[Fe(CN)_6]$ is the most effective.

Which of the following compounds has the highest coagulating power for a ferric hydroxide sol?
