How to determine boiling point chemistry
WebThe measurement of melting points is a relatively straightforward procedure that is carried out to determine the purity of a compound or to assist with its identification. A pure compound will melt over a relatively narrow temperature range, impurities both lower and widen the temperature range over which a compound ... WebSince 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: ΔT b = 2 × (0.52 o C/molal) × (0.619 molal) = 0.643 o C. Boiling point of the solution = boiling point of pure solvent + boiling point elevation. = 100 o C + 0.643 o C = 100.643 o C.
