As per hardy-schulze formulation, the flocculation values of the following for haemoglobin sol are in the order

Options

A. `AlCl_3 gt K_3 [Fe(CN)_6] gt K_2 CrO_4 gt KBr = KNO_3`
B. `K_3 [Fe(CN)_6 ] lt K_2 CrO_4 lt KBr = KNO_3 = AlCl_3`
C. `K_3 [Fe(CN)_6 ] gt Al Cl_3 gt K_2 CrO_4 gt KBr gt KNO_3`
D. `K_3 [Fe(CN)_6 ] lt K_2 CrO_4 lt Al Cl_3 lt KBr lt KNO_3`

Explanation

According to Hardy-Schulze rule,
Coagulation value or flocculation value `1/(Coagu)`
Example
In the Coagulation of the positive sol, the flocculating power is in the order- `F_6e_4S_4`
