Overview

Solutions are homogeneous mixtures of two or more substances. The chapter covers the types of solutions, ways of expressing concentration, behaviour of gases in liquids, vapour pressure and Raoult's law, ideal and non-ideal solutions, azeotropes, colligative properties, osmotic pressure, and abnorma

Key Concepts

A solution is a homogeneous mixture

A solution is a homogeneous mixture of two or more substances. The component present in excess and having the same physical state as the solution is t

Solutions may be gas

Solutions may be gas-gas, gas-liquid, gas-solid, liquid-liquid, liquid-solid, solid-solid, and other combinations. Binary, ternary, and quaternary sol

Mass percentage

Mass percentage, volume percentage, ppm, g/L, molarity, formality, molality, and mole fraction are used to describe composition. Molarity, normality,

At constant temperature

At constant temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas. In mole-fraction form, p = KH·χ, whe

For volatile liquids

For volatile liquids, the partial vapour pressure of each component is proportional to its mole fraction: pi = pi°·χi. For a non-volatile solute, vapo

Learning Objectives

  • Define a solution, solute, and solvent
  • Classify solutions according to the physical states of solute and solvent
  • Express concentration using mass percentage, volume percentage, ppm, g/L, molarity, formality, molality, and mole fraction
  • Use relations between concentration units for numerical problems
  • Explain solubility of gases in liquids using Henry's law
