Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope. WebThe boiling point elevation constant has the units °C per molality, and is different for each solvent. For water, the constant is 0.512 °C per molal. So, a 2.00 molal aqueous solution …

WebFirst, let's say we have a compound with a boiling point of 100oC at 1mm Hg pressure. What is the boiling point at 760mm Hg? To do this we need to draw a line from 100oC on scale A (left side, observed boiling point) to 1.0 mm Hg on scale C (right side, pressure "P" mm). We can then read off the boiling point at 760 mm on line B, it is about 280oC. WebAs such, the normal boiling point of the solution is higher than that of the pure solvent. This property is called boiling point elevation.
