The coagulation value in millimoles per ...

The coagulation value in millimoles per litre of the electrolyes 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

I gt II gt III

B

II gt I gt III

C

III gt II gtI

D

III gt I gt II

Text Solution

Verified by Experts

Lower is the coagulation value, higher is the coagulation power. Therefore, coagulating power is in the order : `III(MgSO_4) gt II(BaCl_2) gt I (NaCl)`
