What is the tread in b.p. and f.p. temperatures of equimolar solutions of urea,NaCI, `K_(2)SO_(4), K_(2)[FeCN_(6)]` ?

Text Solution

Verified by Experts

Elevation in boiling point temperature `(DeltaT_(b))` is directly proportional to the number of solute particles. i.e., more the number of particles, higher will be boiling point of the solution.
Trend in b.p. of equimolar solution : `urealtNaCIltK_(2)SO_(4)ltK_(3)[Fe(CN)_(6)]`
Depression in freezing point temperature `(DeltaT_(f))` is also apropotional to the number of solute particlis. i.e. more the number of particles, more will be the depression in the freezing point of the solution.
Trend in f.p. of equimolar solution : `urealtNaCIltK_(2)SO_(4)ltK_(3)[Fe(CN)_(6)]`
