The coagulation values in millimoles per litre of the electrolytes used for the coagulation of $$As_2S_3$$ are given below: I. $$(NaCl) = 52$$ II. $$(BaCl_2) = 0.69$$ III. $$(MgSO_4) = 0.22$$ The correct order of their coagulating power is :

AIII > II > I
Correct Answer
BIII > I > II
CI > II > III
DII > I > III

Solution

$$Coagulation\ power\ \ \alpha\ \ \dfrac{1}{cogulation\ value}$$

Hence, option A is correct.
