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

`IgtIIgtIII`

B

`IIgtIgtIII`

C

`IIIgtIIgtI`

D

`IIIgtIgtII`

Text Solution

Verified by Experts

The correct Answer is:
C
Coagulating Power `prop1/("Coagulation value")`
So, `underset((III))(MgSO_(4))gtunderset((II))(BaCl_(2))gtunderset((I))(NaCl)`
