Question

calculate the degree of dissociation of weak electrolyte AB inaqeous solution if Tf=0.20k for 0.1 molality solution kf=1.86​

Answer 1

Answer:

Tf=i×Kf×m

0.20=i×1.86×0.1

i=0.20/0.86

i=approximately 1

Explanation:

1. for weak electrolyte degree of dissociation is nearly equal to vant-off factor
