<Chapter 9 Freezing-Point Depression and Boiling-Point Elevation 6 of 11 A Review Constants Periodic Table The changes in boiling point (AT) or freezing point (AT) in degrees Celsius from a pure solvent can be determined from the equations given here, respectively AT m x Kb moles of solute kilograms of solvent x Kb Since pure water boils at 100.00 °C, and since the addition of solute increases boiling point, the boiling point of an aqueous solution. To, will be moles of solute AT: m x K kilograms of solvent x Ki where m is the molality of the solution, and Ky and Kf are the boiling-point-elevation and freezing-point-depression constants for the solvent, respectively. For water, To = (100.00+ AT) °C Since pure water freezes at 0.00 °C, and since the addition of solute decreases freezing point, the freezing point of an aqueous solution, I will be Ti = = (0.00 - AT) °C Kp = 0.512 °C kg solvent mol solute Part A KA = 1.86 °C. kg solvent mol solute What is the boiling point of a solution made using 785 g of sucrose, C12H22011, in 0.275 kg of water, H2O?
