Boiling point elevation in real life
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: … WebK b is the molal boiling point elevation constant, and m is the molal concentration of the solute in the solution. Note that the molal boiling point elevation constant, K b, has a specific value depending on the identity …
