An aqueous solution of a salt MX2 at certain temperature has a Van't Hoff factor of 2. What is the degree of dissociation for this solution of the salt?
  1. 0.50
  2. 0.33
  3. 0.67
  4. 0.80

Solution

α=i-1k-1

=2-13-1=12=0.50

Here,

i= van't hoff factor

α =degree of dissociation

k= total number of ions(dissociated)
