The electrolyte having maximum flocculation value for `AgI//Ag^(+)` sol,is

Options

A. `Na_3PO_4`
B. `Na_2SO_4`
C. `Na_2S`
D. `NaCl`

Answer

D

Explanation

Flocculation value is inversely proportional to flocculation, power
For the flocculation of posilively charged Sol `PO_4^(3-)` ions have maximum flocculation power while `Cl^(-)` have minimum flocculation power. Hence, NaCl will have maximum flocculation value.
