Van't Hoff factor is 1.92 for `MgI_(2)` solution with concentraition 0.2M then the degree of dissociation of salt at this concentration is :-

A

`46%`

B

`96%`

C

`30.67%`

D

`64%`

Text Solution

Verified by Experts

The correct Answer is:
A
`MgI_(2)toMg^(2+)+2I^(-)`
`alpha=(i-1)/(n-1)=(1.92-1)/(3-1)=(0.92)/(2)=0.46`
`=46%`
