Colligative property

1. What is a colligative property? Use complete sentences.

2. Explain why freezing point of a solution depresses and boiling point elevates compared to the pure solvent. Use diagrams and complete sentences.

3. If the density of milk is 1.035 g/cm3 and the freezing point is -0.250 oC, calculate the Kf for milk. Assume the whipping cream is milk and therefore your pure
solvent is milk. The formula for sugar is C12H22O11. Use one dry 1 oz = 28.35 g. Show all your work!

4. How would using sodium carbonate effect the temperature depression? Explain your answer.

6. The freezing point of t-butanol is 25.50 oC and has a Kf of 0f 9.1 oC/m. Usually t-butanol absorbs water on exposure to air. If the freezing point of a 10.0
g sample of t-butanol is 24.59 oC, how many grams of water present in the sample?

 

 

Colligative property

Colligative properties are properties of a solution that depend only on the concentration of solute particles. They include changes in the vapor pressure, boiling point, and freezing point of the solvent in the solution. The boiling point of a solution is higher than the boiling point of a pure solvent and the freezing point of a solution is lower than the freezing point of a pure solvent. However, the amount to which the boiling point increases or the freezing point decreases depends on the amount of solute that is added to the solvent. Both the boiling point elevation and the freezing point depression are related to the molality of the solution.

 

Twimble declared Finch as his decision to head the sorting room, anyway the book cautions not to remain in the sorting room excessively long. Finch prescribes Frump for the advancement rather than himself, to benefit the organization. Twimble is hesitant to advance Frump due to his lethargy, yet Frump vows to be a decent representative (“The Company Way (Reprise)”).
