Question

what is the answer for this question?

Answer 1

I think the answer is option 4

Answer 2

Answer should be option D

degree of dissociation = i-1/n-1

Here n =3 since SrCl2 disscoates as Sr2+ and 2Cl-
i = 1.6

Substituting the values

degree of dissociation = 1.6-1/3-1 = 0.6/2 = 0.3

Percentage dissociation = 0.3*100 = 30%
