WebBoiling point of the solution = boiling point of pure solvent + boiling point elevation = 100 o C + 0.643 o C = 100.643 o C. Therefore, the boiling point of the 3.5% NaCl solution is 100.643 o C. Conclusion The addition of heat causes the transformation of the liquid into its vapour without raising the temperature. WebBecause the presence of solute particles decreases the vapor pressure of the liquid solvent, a higher temperature is needed to reach the boiling point. This phenomenon is called boiling point elevation. For every mole of particles dissolved in a liter of water, the boiling point of water increases by about 0.5°C. someone is watching you tess james-mackey https://gentilitydentistry.com
