What temperature would a 2m water solution of CaCl2 boil at? (SW) Kb water is .52 BP water is 100oC ATb = (i)(kb)(m)

Question

 What temperature would a 2m water solution of CaCl₂ boil at?  

K_b water is .52    BP water is 100^oC     AT_b = (i)(k_b)(m)

Answer 1

ΔT = imK

ΔT = change in temp =?

i = vant Hoff factor = 3 for CaCl2

m = molality = 2

K = bp constant = 0.52

ΔT = (3)(2)(0.52) = 3.12 degrees

New boiling point = 100+ 3 = 103 degrees C
