The degree of dissociation of an electro...

The degree of dissociation of an electrolyte is `alpha` and its van't Hoff factor is `i`. The number of ions obtained by complete dissociation of 1 molecules of the electrolyte is `:`

A

`(i+alpha-1)/(alpha)`

B

`i-alpha-1`

C

`(i-1)/(alpha)`

D

`(i+1+alpha)/(1-alpha)`

Text Solution

Verified by Experts

The correct Answer is:
1
`i=1+(n-1)alpha" "`so `n=(i+alpha-1)/(alpha)`
