Based on an equimolar mixture of water and ethanol and your knowledge of colligative properties (boiling point elevation), calculate the theoretical boiling point of your ethanol/water mixture. You will be distilling an equimolar mixture of ethanol and water. Based on its density at room temperature, calculate the correct volume of ethanol you will need to mix with 10.0 mL of water to make an equimolar mixture

In which of the following pairs of properties are both members of the pair colligative properties? density, boiling point vapor pressure, flammability solubility, freezing point freezing point, boiling point Question 6 Which of the following solutions would always contain 5.00 g of solute per 45.0 g of solvent? 11.1% (m/m) solution 20.0% (m/m) solution Ο Ο Ο 10.0% (m/m) solution 25.0% (m/m) solution
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...

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)...
