Q:10

The coagulation values in millimoles per litre of the electrolytes used for the coagulation of As₂S₃ are given below:

I. (NaCl) = 52, II. (BaCl₂) = 0.69 III. (MgSO₄) = 0.22

The correct order of their coagulating power is

III > I > II

I > II > III

II > I > III

III > II > I

Explanation:

$Coagulation \ power \propto \dfrac{1}{Coagulation \ value}$

Higher the coagulation power, lower is the coagulation values in millimoles per litre.

MgSO₄ > BaCl₂ > NaCl.
