The coagulation values in millimoles per...

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 gt I gt II`

B

`I gt II gt III`

C

`II gt I gt III`

D

`III gt II gt I`

Text Solution

Verified by Experts

Coagulating power varies inversely with the coagulating value. Thus the other of coagulating power is -`MgSO_(4) gt BaCl_(2) gt NaCl`
