The chapter Solutions in Class 12
Chemistry includes the following main topics:
1. Types of solutions: This includes
discussion about three types of solutions based on the physical state of the
solute and solvent such as solid-solid, solid-liquid, and gas-liquid.
2. Concentration of solutions: This
topic covers the various ways in which the concentration of a solution can be
expressed, including mass percentage, mole fraction, molarity, molality, and
normality.
3. Solubility curves: This topic
discusses the solubility of different substances as a function of temperature
and how solubility curves can be used to determine the concentration of a
solution.
4. Colligative properties of
solutions: This topic deals with the changes in the physical properties of a
solvent due to the addition of a solute, such as lowering of vapor pressure,
elevation of boiling point, depression of freezing point, and osmotic pressure.
5. Raoult's Law: This topic is
concerned with Raoult's Law which states that the partial vapor pressure of
each component in a solution is directly proportional to its mole fraction in
the solution.
6. Henry's Law: This topic covers
Henry’s Law which states that the amount of a gas dissolved in a liquid is
directly proportional to the partial pressure of the gas above the liquid.
7. Abnormal molar masses: This topic
describes the effect of the association and dissociation of solute molecules on
the molar mass of the solution.
8. Applications of solutions: This
topic includes applications of solutions in various fields such as medicine,
metallurgy, and environmental science.
These are the main topics covered in
the chapter Solutions of Class 12 Chemistry.
