Which of the following solution will have lowest vapour pressure? A solution of sucrose is 34.2%. The volume of solution containing one mole of solute. How much solvent using percentage weight/weight and percentage weight/volume composition will be used to prepare 5% glucose solution? What are the units of mole fraction and how can we calculate mole percentage? How can your explain the formation of homogeneous mixture? Suggest the method to separate the following mixtures a. Alcohol and water b. Water and Benzene
Between Ideal and None-ideal Solutions giving examples? How can you relate the state of dynamic equilibrium with re-crystallization? Lowering of vapour pressure in 8g of urea 18g of glucose and 34.2 g of sucrose in 1 Kg water will be the same why? How can it be predicted that process of dissolution will be endothermic or exothermic? Ion with high charge density (change/unit area) has a greater ability to attract polar water molecules than ions with smaller charge density why? Explain why l attice energy of ionic solids is always higher than molecular solids?
