公式
## 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.
计算示例
1 m glucose (i=1) in water.
- 01delta_Tb = 1 × 0.512 × 1 = 0.512 C
- 02New BP = 100 + 0.512 = 100.512 C
常见问题
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.
