Chapter Summary

--- PAGE 1 --- Unit 1 Solutions Objectives After studying this Unit, you will be able to * describe the formation of different types of solutions; * express concentration of solution in different units; * state and explain Henry's law and Raoult's law; * distinguish between ideal and non-ideal solutions; * explain deviations of real solutions from Raoult's law; * describe colligative properties of solutions and correlate these with molar masses of the solutes; * explain abnormal colligative properties exhibited by some solutes in solutions. Almost all processes in body occur in some kind of liquid solutions. In normal life we rarely come across pure substances. Most of these are mixtures containing two or more pure substances. Their utility or importance in life depends on their composition. For example, the properties of brass (mixture of copper and zinc) are quite different from those of German silver (mixture of copper, zinc and nickel) or bronze (mixture of co…
