Vedclass · Answer

(C) According to the $Hardy-Schulze$ law,the coagulating power of an electrolyte depends on the valency of the ion carrying a charge opposite to that of the colloidal particles.For a positive colloid,the negative ion with the highest valency is the most effective coagulating agent.Comparing the negative ions:$Cl^-$ (valency $1$)$SO_4^{2-}$ (valency $2$)$[Fe(CN)_6]^{4-}$ (valency $4$)Since $[Fe(CN)_6]^{4-}$ has the highest valency,$K_4[Fe(CN)_6]$ is the most effective electrolyte.

Most effective electrolyte to coagulate the positive colloid is
