Change in Boiling Point of Solvent Calculator

Formula

The formula to calculate Change in Boiling Point of Solvent (Δbp) is:

\[ Δbp = Kb \cdot m \]

Where:

\(Δbp\) is the Change in Boiling Point of Solvent.
\(Kb\) is the Molal Boiling Point Elevation Constant.
\(m\) is the Molal Concentration of Solute.

Definition

Change in Boiling Point of Solvent is the change in the boiling point of the solvent after adding a solute to it.

Molal Boiling Point Elevation Constant is the constant of elevation in boiling point of solute and has a specific value depending on the identity of the solvent.

Molal Concentration of Solute is the molal concentration of the solute which is added to the solvent.

How to calculate Change in Boiling Point of Solvent

Let's assume the following values:

Molal Boiling Point Elevation Constant (Kb) = 4.8
Molal Concentration of Solute (m) = 2.5 Mole per Liter

Using the formula:

\[ Δbp = Kb \cdot m \]

Evaluating:

\[ Δbp = 4.8 \cdot 2.5 \]

The Change in Boiling Point of Solvent is 12 Kelvin.
