  • Boiling Point Elevation
    Phenomenon where adding a solute to a solvent causes an increase in the solvent's boiling point.
  • Normal Boiling Point
    Temperature at which a pure solvent transitions to vapor before any solute is added.
  • Boiling Point of Solution
    Temperature at which a solvent containing dissolved solute transitions to vapor.
  • Solute
    Substance dissolved in a solvent, responsible for altering the boiling point of the mixture.
  • Solvent
    Primary liquid in which a solute is dissolved, determining the initial boiling point.
  • Delta Tb
    Symbol representing the change in boiling point due to the presence of a solute.
  • van't Hoff Factor
    Number indicating how many particles a solute produces in solution, affecting boiling point change.
  • Boiling Point Constant
    Proportionality value (kb) unique to each solvent, used in calculating boiling point elevation.
  • Molality
    Concentration unit defined as moles of solute per kilogram of solvent, used in colligative property calculations.
  • Colligative Properties
    Physical properties of solutions that depend on solute particle quantity, not their identity.
  • Electrolyte
    Compound that dissociates into ions in solution, increasing the van't Hoff factor above one.
  • Nonvolatile Compound
    Substance with negligible vapor pressure, not contributing to the vapor phase above a solution.
  • Covalent Compound
    Molecule formed by shared electrons, typically yielding a van't Hoff factor of one in solution.
