Over the next few pages you will be introduced to the equations in the context of the specific properties, but for now, simply note the similarities in structure Colligative Properties. • vapor pressure lowering. Raoult's Law: PA = XAP°A. • boiling point elevation. ?Tb = Kbm. • freezing point depression. ?Tf = Kfm. • osmotic pressure. " = n. V. #. $. %. &. ' ( RT = M RT. Colloids. 1. Mary J. Bojan. Chem 110. Test Question. Which of the following aqueous solutions has the greatest total 1 Jan 2013 Colligative Properties. 12.3 Colligative Properties. Changes in solvent This new developed property is called Colligative Property; a method of counting the number of solute in solution. . Note that; AT = m • Kf,b Where K is only a function of the solvent !!! Reason for the difference in colligative properties colligative properties to measure the molecular weight of polymers. Because colligative properties depend on the number of molecules, we expect, and will show, that colligative property experiments give a number average .. B/2 (Note that in this approximation to ln(1 ? vB) we keep one more term than we have used in www.ncerthelp.com (Visit for all ncert solutions in text and videos, CBSE syllabus, note and many more). Chemistry Notes for class 12 Chapter 2. Solutions. Solution is a . Colligative properties are those properties which depends only upon the number of solute particles in a solution irrespective of their nature. Relative Consider volatile solvent: add a bit of solute (salt or sucrose), liquid phase becomes a mixture. - liquid freezes > solid is pure solvent. - liquid evaporates > vapour is also pure solvent. For solvent: > melting point reduced (ice +salt). > boiling point increased. The increase/decrease depends only on molar concentration Describe meaning of colligative property. ? Use Raoult's law to determine vapor pressure of solutions Colligative properties have common origin. ? Colligative properties depend on amount of solute but do not K b is the molal boiling point elevation constant. ? Note: molality is calculated in terms of particles. mKT b b. =. Note: •. Used when both the components of solution are in liquid phase. •. Total volume of solutions is not equal to sum of volumes of solute and solvent as same solute particles occupy empty .. Colligative properties: The properties of solutions that depend only on the number of solute particles in solution and not on the Colligative properties. CH102 General Chemistry, Spring 2014, Boston University. There are four colligative properties. • vapor-pressure lowering. • boiling-point elevation. • freezing-point depression. • osmotic pressure. Each of these properties is due to the effect of solute on entropy changes and so spontaneity. We will Note: we had mole fraction in gases, but the same idea appli$
