A liquid’s boiling point can be determined using the capillary method, where an inverted capillary is placed in the liquid of interest and the liquid is heated. As the temperature increases, the air in the capillary escapes and is replaced by the vapor of the liquid. crypt regenerationWebSince 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. cryptofeesaverWebHow do you find the boiling point elevation on a graph?What is elevation in boiling point graph explanationcolligative propertieselevation of boiling pointel... cryptofear look into bitcoinWebSep 7, 2024 · How do you solve for boiling point?
