Ch#10-Solutions and Colloids, FSc Pre-Engineering Notes Chemistry 2016-17 New Course FBISE

In Tenth chapter (Ch#10-Solutions and Colloids), the students will learn about  the different concentration units of solutions (percentage composition, molarity, molality, mole fraction, ppm, ppb, ppt) from the given data, distinguish between hydrophilic and hydrophobic molecules, predict the nature of solutions in liquid phase in the given examples (w.r.t. miscible, immiscible, partially miscible solution), interpret the solubility graph on the basis of temperature for different solutions, state Raoult’s law (all three definitions), identification of volatile and non-volatile components of solution by plotting graph, draw a graph using Raoult’s law from the given data, colligative properties of liquids with examples, lowering of vapour pressure, elevation of boiling point and depression of freezing point, calculation of molar mass of a substance using ebullioscopic and cryoscopic methods, difference between osmotic pressure and reverse osmosis, the properties of colloids, suspension and solution, the types of colloids, comparison of the characteristics of colloids and suspension that distinguish these from solution and classification of the given substances as solutions, colloids or suspensions.
