https://www.chemcontent.com/ 3 SOLUTIONS Introduction: In this chapter, we will discuss about liquid solutions and their formation. This will be followed by studying the properties of solutions, like vapour pressure and colligative properties. We will begin with types of solutions and expressions for concentration of solutions in different units. Thereafter, we will state and explain Henry’s law and Raoult’s law, distinguish between ideal and non-ideal solution and deviation of real solutions from Raoult’s law. We will also discuss abnormal colligative properties alongwith association and dissociation of solute. Types of Solutions All the three states of matter (solid, liquid and gas) may behave either as solvent or solute. When a solution is composed of only two chemical substances, it is termed as binary solution. Depending upon the state of solute or solvent, binary solutions can be classified as Some Important Definitions • Mixture - When two or more chemically non-reacting substances are mixed, they form mixture. • Heterogeneous Mixture - It consists of distinct phases, and the observed properties are just the sum of the properties of individual phases. • Homogeneous Mixture - It consists of a single phase which has properties that may differ from one of the individual components. • Solution - The homogeneous mixture of two or more components such that at least one component is a liquid is called solution.
