Boiling Point Elevation vs Ebullioscopic Constant (Kb)
Formula
## How to Calculate Boiling Point Elevation ### Formula **delta_Tb = i × Kb × m** For water, Kb = 0.512 C-kg/mol. The boiling point rises when solute is added.
Exemplo Resolvido
1 m glucose (i=1) in water.
- 01delta_Tb = 1 × 0.512 × 1 = 0.512 C
- 02New BP = 100 + 0.512 = 100.512 C
Perguntas Frequentes
What is boiling point elevation?
A colligative property where a solution boils at a higher temperature than the pure solvent.
Why does adding salt raise boiling point?
Salt ions lower vapor pressure, so higher temperature is needed to reach boiling.
What is Kb for water?
0.512 C-kg/mol. Other solvents: benzene 2.53, acetic acid 3.07.
