Notes On Gaseous State This page provides you all details about the gaseous state of BSc standard. Concerned problems will be solved at the end of each concept. Continue till the end to find the easiest explanation of every concept you need in this regard . Postulates of Kinetic Theory of Gases: 1. All gas consist of a very large number of minute particles, called molecules. 2. The gas molecules are extremely small in size and are separated by large distance. The actual volume of the gas molecules is thus negligible as compared to the total volume occupied by the gas. 3. The pressure exerted by the gas is due to the bombardment of the molecules on the walls of the vessel. 4. The gas molecules collide with one another and also with the walls of the vessels. These collisions are perfectly elastic and there is no loss of energy during these collisions. 5. The distance between the gas molecules are very large. Thus, there is no effective force of attraction or r
Ionic Equilibrium Equilibrium established between the ions and the undissociated electrolyte in a solution is called the ionic equilibrium. In other words, Ionic equilibrium is the study of solutions of electrolyte. Electrolyte: Substances which furnish ions in aqueous solution or in fused state is called the electrolytes. These substances conduct electricity in their aqueous solutions or in their fused state. Degree of dissociation (α): The number of molecules dissociated out of total number of molecules originally taken is called the degree of dissociation. Mathematically, It is expressed in percentage or as fraction or decimals. If 40 molecules are dissociated out of 100 molecules than the degree of dissociation is expressed as 40% or 0.4. Strong Electrolytes: These substances dissociate almost completely into ions in aqueous solutions and hence are good conductor of electricity. Ex: KCl, NaCl, KOH, NaOH etc. Weak Electrolytes: These substances dissociate to a smal
