$NaCl$

Vedclass · Answer

(A) According to the Hardy-Schulze law,the flocculating value is inversely proportional to the valency of the coagulating ion,i.e.,$	ext{Flocculating value} \propto \frac{1}{z}$,where $z$ is the valency of the coagulating ion.$Fe(OH)_3$ is a positively charged sol,so it is coagulated by negative ions.The negative ions present in the given electrolytes are:$A) Cl^-$ (valency = $1$)$B) S^{2-}$ (valency = $2$)$C) PO_4^{3-}$ (valency = $3$)$D) SO_4^{2-}$ (valency = $2$)Since $Cl^-$ has the lowest valency $(z=1)$,it will have the maximum flocculation value. Therefore,$NaCl$ has the maximum flocculation value.
