Which of the following regarding colligative properties of a solution is NOT correct? a. The temperature range over which a solution remains liquid is larger than that of the pure solvent due to the presence of solute particles. Cb. Vapor pressure reduction is a colligative property. c. Colligative properties depend on the concentration of the particles dissolved in the solvent. Cd. The freezing point of a solution increases as the concentration of solute increases. e. The change in the boiling...
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...

24. Circle one word inside each set of parentheses in the following statement: (Solutions, colloids, suspensions) contain the smallest particle size and (solutions, colloids, suspensions) contain the largest particle size. Which statement about colligative properties is incorrect? A. Solutes will lower the freezing point and raise the boiling point of a solvent. B. Colligative properties depend only on the number of dissolved particles and not on their size or chemical properties. C. Colligative properties involve only charged particles in solution....
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...
