🌡️ Boiling Point Calculator
Calculate boiling point elevation using ΔT = i·Kb·m. Determine the new boiling point when a solute is dissolved.
Boiling Point Elevation
Boiling point elevation is a colligative property described by the formula ΔT = i·Kb·m, where ΔT is the change in boiling point, i is the van't Hoff factor (number of particles the solute dissociates into), Kb is the ebullioscopic constant of the solvent (°C·kg/mol), and m is the molality of the solution (mol solute/kg solvent).
Understanding the Van't Hoff Factor
The van't Hoff factor (i) represents the number of particles a solute forms in solution. For non-electrolytes like glucose, i = 1. For NaCl, i = 2 (Na⁺ and Cl⁻). For CaCl₂, i = 3. This factor directly affects the magnitude of the boiling point elevation.
