Which of the following electrolyte will have maximum flocculation value for $Fe(OH)_3$ sol?

(a) $NaCl$

(b) $Na_2S$

(c) $(NH_4)_3PO_4$

(d) $K_2SO_4$

Toolbox:
• Flocculation value = $\frac{\text{1}}{\text{Coagulating Power}}$

$Fe(OH)_3$ is positively charged. Hence $Cl^-$ ions with minimum opposite charge will have maximum flocculation value (minimum coagulating power)
