5.1: Introduction to solution
-
The solution, i.e., a homogeneous mixture is described along with the concepts of solvent, solute, and types of solution. Water as a solvent and its dissolution mechanism are described.
-
-
5.2: Solubility
-
Solubility, i.e., the maximum amount of solute that can dissolve in a given amount of solvent, is described along with the terminologies. Solubility guidelines that help in predicting the solubility of ionic compounds in water are listed.
-
-
5.3: Electrolytes
-
Electrolytes, i.e., the compounds that dissolve in water and dissociated partially or fully into ions are described. Equivalent i.e., a mole of charge is also introduced along with body fluids and their concentration.

5.4: Concentration of solutions
-
Concentration, i.e., the amount of solute in a given amount of solution, is described along with its different units. Preparation of and dilution of the solution are also presented.

5.5: Osmosis
-
Osmosis, i.e., the passage of water and small molecules across a semipermeable member with a net flow towards a more concentrated solution is described. The role of osmosis in water purification, in living systems like excretion of wastes by kidneys, are also described.
