Solutions Class 12 CBSE Revision Notes
This article deals with solutions chemistry class 12 notes pdf. In normal life, only on some occasions do we come across pure substances. Furthermore, most of these mixtures contain multiple pure substances. Moreover, their utility is dependent on their composition. For example, the properties of brass are quite different in comparison to that of bronze. Liquid solutions and their formations certainly play an important role in chemistry.
Solutions refer to homogenous mixtures that contain two or more components. Furthermore, the homogenous mixture means the composition and properties are uniform throughout. The classification of solutions can take place as solid, liquid, and gaseous. Moreover, the expression of the concentration of a solution can take place in terms of molarity, molality, mole fraction, and percentages. Also, Henry’s law governs the dissolution of a gas in a liquid. Thus, solutions chemistry class 12 notes pdf will explain this all in detail.

Sub-topics covered under Solutions
- Abnormal Molar Masses– Abnormal molar masses refer to molar masses that are higher or lower than the expected value.
- Colligative Properties and determination of Molar Mass– Colligative policy refers to certain properties of solutions and molar mass refers to the mass of a compound’s sample divided by substance’s amount in that sample.
- Expressing Concentration of Solutions– This part deals with expressing concentrations of solutions.
- Ideal and Non-ideal Solutions– Ideal solution is one where molecules interactions are identical to molecules interactions of a different component while non-ideal is one which does abide by those rules.
- Osmosis and Osmotic Pressure– Osmosis refers to the net flow of solvent molecules by a semipermeable membrane.
- Solubility– This refers to the ability of a substance to dissolve in a solvent.
- Types of Solutions– There can certainly be many types of solutions depending on various basis.
- Vapour Pressure of Liquid Solutions– This refers to the pressure by the vapours on the solvent when kept in equilibrium.
