The van 't Hoff factor i (named after Dutch chemist Jacobus Henricus van 't Hoff) is a measure of the effect of a solute on colligative properties such as osmotic pressure, relative lowering in vapor pressure, boiling-point elevation and freezing-point depression. The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. For most non-electrolytes dissolved i… WebApr 10, 2024 · The various types of colligative properties are: Freezing point depression. Boiling point elevation. Osmotic pressure. Relative lowering of vapor pressure. The word ‘colligative’ is derived from the Latin word Colligatus. Colligatus …

WebThe van't Hoff factor is the number of particles that a single solute will dissociate into when added to a solution. MgCl 2 will dissociate into three particles: 1 Mg 2+ cation and 2 Cl-anions. Since 2m of MgCl 2 has the highest molality as well as the largest van't Hoff factor out of the options, it will result in the highest boiling point.
