Solution
The correct option is C all of these For the given electrolyte AxBy, the degree of dissociation 'α' can be given as
AxBy→xA+yB 1-αxαyα
Total moles =1+(x+y−1)α
i= moles after dissociation/initial moles =+(x+y−1)α1=1+(x+y−1)α
(A) α=i−1x+y−1
(B) i=(1−α)+xα+yα
(C) a=1−i1−x−y
Here, i is the Van't Hoff factor and x and y are the number of cations and anions obtained respectively on the dissociation of 1 molecule of electrolyte.
