Coagulation

Question

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

I > II > III

Solution

The correct option is C III > II > I
$C o a g u l a t i n g p o w e r \propto \frac{1}{C o a g u l a t i o n v a l u e}$
Lower the coagulation value, higher is the coagulating power so, the correct order is :
$M g S O_{4} (I I I) > B a C l_{2} (I I) > N a C l (I)$
