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

`III gt II gt I`

B

`IIII gt I gt II`

C

`I gt II gt III`

D

`II gt Igt III`

Text Solution

Verified by Experts

The correct Answer is:
A
Coagulating power `prop (1)/("Coagulation value")`
Hence, the order is `III gt II gt I.`
