How is the van't Hoff factor used in the freezing point depression formula?
Adelta Tf = i Kf m
Bdelta Tf = Kf m / i
Cdelta Tf = Kf + i m
Ddelta Tf = i / Kf m
Answer & Solution
Correct answer: A. delta Tf = i Kf m
The factor i multiplies the ideal depression to account for dissociation or association.
