 Let’s use the Kb and Kf chart and the above formulae to solve the following problems. Example What will be the freezing point and boiling point of a solution containing 3.8 gms of benzoic acid in 50 gms of chloroform ? Freezing point depression D Tf = 0.623 ´ 4.68 = 2.915 So, the freezing point of chloroform solution - 63.5 - 2.91 = - 66.4150C Boiling point elevation D Tb = 0.623 ´ 3.63 = 2.261 So, the boiling point of chloroform solution 61.2 + 2.261 = 63.460C Example What will be the molecular weight of the solute if a solution prepared from 500 gms of a solute in 3 kg of water has a boiling point elevation f 20C than that of pure water ? ********** Index 8.1 Nature of Solution 8.2 Heat of Solutions 8.3 Concentration of Solution 8.4 Effect of Temperature and Pressure on Solubility 8.5 Boiling Point and Freezing Point of Solution Chapter 9 Follow @Pinkmonkey_com Your browser does not support the IFRAME tag.
