^^(m) of 0.05 M weak electrolyte is "50 ...

`^^_(m)` of 0.05 M weak electrolyte is `"50 Sm"^(2)mol^(-1),0^(@)` of it is `"440 Sm"^(2)" mol"^(-1)`. Calculate `alpha` (degree of dissociation) of the electrolyte. 

Text Solution

Verified by Experts

Degree of dissociation of an electrolyte is given by
`alpha=(^^_(m))/(^^_(m)^(@))`
`"Given :  "^^_(m)="50 sm"^(2)" mol"^(-1)`
`^^_(m)^(@)="440 sm"^(2)" mol"^(-1)`
`"conc "=0.05m`
`alpha=(50)/(440)(cancel(sm^(2)))/(cancel(sm^(2)))(cancel(mol^(-1)))/(cancel(mol^(-1)))`
`alpha=0.
