Imagine two solutions with the same concentration and the same boiling point, but one has ethanol as the solvent and the other has carbon tetrachloride as the solvent. Determine that molal concentration, m (or b),m (or b), and boiling point, Tb.Tb.
Solvent | Normal boiling point (∘C)(∘C) | Kb (∘C/m)Kb (∘C/m) |
---|---|---|
ethanol | 78.4 | 1.22 |
carbon tetrachloride | 76.8 | 5.03 |
