Example: What is the freezing point of a 2 m solution of NaCl in water if the freezing point elevation constant is -1 858 o C /m? Solution: i = 2 Na+ and CL-
What is the formula for the colligative properties of vapor pressure?
Examples of colligative properties are: Vapour Pressure lowering of a solution. Boiling Point elevation. Freezing Point depression.
What is the formula of solution?
Its difference with respect to the vapor pressure of the pure solvent can be calculated as: P∗solvent−Psolution=P∗solvent−xsolventP∗solvent=(1−xsolvent)P∗solvent=xsoluteP∗solvent, which shows that the vapor pressure lowering depends only on the concentration of the solute. As such, it is a colligative property.24 nov. 2022
What are the 4 colligative properties of solutions?
Once the molecular weight of the solute is known, the weight of chemical to dissolve in a solution for a molar solution less than 1M is calculated by the formula: grams of chemical = (molarity of solution in mole/liter) x (MW of chemical in g/mole) x (ml of solution) ÷ 1000 ml/liter.
The equations for the four colligative properties are as follows. T f = − i K f m where T is the change in freezing point of the solution, K is a constant, and m is the molality of the solution measured in kg/mol. i is the van't Hoff factor, which is given by the number of individual ions the solute dissolves into.
