The coagulation values in millimoles per litre of the electrolytes used for the coagulation of As_{2} S_{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:

A $III > I > II$
B $I > II > III$
C $II > I > III$
D $III > II > I$

Solution & Step-by-step Explanation

Coagulating power is inversely proportional to the coagulation value. Coagulating Power \propto \frac{1}{Coagulation Value} Given values: NaCl : 52 BaCl_{2} : 0.69 MgSO_{4} : 0.22 Smallest value (0.22) belongs to MgSO_{4}, so it has the highest power.Largest value (52) belongs to NaCl, so it has the lowest power.Order: III (MgSO_{4}) > II (BaCl_{2}) > I (NaCl).
