What is the boiling point of water at 15 psi? WebAug 30, 2024 · The reagent (titrant) is the solution with a known molarity that will react with the analyte. Procedure The analyte is prepared by dissolving the substance being studied into a solution. The solution is usually placed in a flask for titration. A small amount of indicator is then added into the flask along with the analyte.

WebThe van't Hoff Factor (i) has no units and is simply the number of ions a solute dissociates into per formula unit. Since the change in a colligative property is proportional to the number of solute particles present in solution, then a solute that dissociates into multiple ions will result in a larger change and the van't Hoff factor allows us to factor that in. WebTherefore, 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 Therefore, the boiling point of the 3.5% NaCl solution is 100.643 o C.
