The degree of dissociation ( ) of a weak electrolyte, A_x B_y is related to van't Hoff factor (i) by the expression:

Options

  1. A= i-1 x+y+1
  2. B= x+y-1 i-1
  3. C= x+y+1 i-1
  4. D= i-1 (x+y-1)

Correct answer

D. = i-1 (x+y-1)

Step-by-step solution

aligned & i=1- +n =1+ (n-1) & i-1 n-1 = & A_x B_y x A^ +y +y B^ -x & n=x+y aligned So = i-1 x+y-1
