Boiling point by elevation
WebThe boiling point elevation constant of water is 0.512 o C.kg/molal. Since NaCl dissociates into 2 ions, the Van’t Hoff factor for this compound is 2. Therefore, the boiling point elevation (ΔT b) can be calculated as follows: o C/molal)*(0.619 molal) = 0.643 o C. Boiling point of the solution = boiling point of pure solvent + boiling point ...
