Actually I want in description ...
k.
We assume the solvent is water.
Normal boiling point at 1 atm is 100°C.
We assume that the pressure is
constant.
* b solute
Raoults law: AT b K b*
K_b R (T_b) M/ AHV Ebullioscopic
constant (for a solvent)
R: Universal gas constant
T_bboiling point of pure solvent
M Molar mass
AHv - Latent Heat of vaporization
Kb 0.512 °C /molal for water
i number of solute particles in
solution (dissociated ions or single
compound) per molecule
bsolute molality

For Na CI:
1.024C, T b 101.512 °C
For Ba CI2 :
for AICI3
i2 (or 1.9): AT_b
T b 101.536 C
T b 102.048C
