Homework Answers
colligative properties are properties which depend upon the concentration of solute molecules present in solution
These include
vapor pressure lowering
boiling point elevation
freezing point depression
osmotic pressure
in above problem option d is not correct statement about the colligative properties because poitn sat that freezing point of solution increase which is not correct
there is decrease in freezing point when a solute is added to solvent
for example when salt is added to water,then as a result there is decrease in freezing point noticed as compared to te pure solvent
because the chemical potential of the solvent in the mixture is lower than that of the pure solvent

What is the relationship between the moles of solute and the
mass of solute?
Rewrite the molality expression in terms of grams and molecular
weight.
Background:
Properties that depend on the concentration of particles in solution are called colligative properties. The number of particles in a solvent can affect the freezing or boiling point of solvent. To express the effect of concentration on freezing point or boiling point, molality is used in place of molarity. Molality (m) is the number...

Assignment Four Colligative properties refer to properties of the solvent that are affected by the presence/absence of solute particles. As such, they are dependent on the physical reaction of the solute and the solvent—there are no chemical reactions involved. All responses to the following questions should use language and terms that a high school senior that hasn't taken AP chemistry. 1) Why does the addition of solute decrease the melting point, and increase the boiling point of the solvent? 2)...

Drop at freezing point: A student performed the colligative properties experiment for which he measured 50.00mL of a solvent and weighed it giving a mass of 75.25g. I determined that the freezing point of the pure solvent was 1.00C. Then he added 0.30g of an unknown solid and determined that the freezing point of solution was -1.00C. The Kf of the pure solvent is 20.2C / m. Use the information presented above to answer the following questions: 1. What is...

Colligative properties, such as boiling point elevation, depend on the number of dissolved particles in solution. For nonelectrolytes, no dissociation occurs, and so you can use the number of moles of solute to calculate both molality and molarity. In contrast, electrolytes dissociate, and therefore the molality and molarity must be calculated based on the number of moles of dissociated particles or ions. There are two ions per formula unit of NaCl. Therefore, we would expect the freezing-point depression ΔTf of...
