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. Webthe boiling point of the solvent in a solution is higher than that of the pure solvent; the freezing point (melting point) of the solvent in a solution is lower than that of the pure solvent. We have looked at this with water as the solvent, but using a different solvent would make no difference to the argument or the conclusions. birgit trifonov https://pickfordassociates.net
