Question

The coagulation values in millimoles per litre of the electrolytes used for the coagulation of $A s_{2} S_{3}$ are given below :
(I) for $N a C l, i t i s 52,$
(II) for $B a C l_{2}, i t i s 0.69,$
(III) for $M g S O_{4}, i t i s 0.22$
The correct order of their coagulating power is

III > II > I

Solution

The correct option is A III > II > I
Coagulation power $\propto \frac{1}{c o a g u l a t i o n v a l u e}$
So, the order is III > II > I
