Solution class 12 chemistry most important objective questions for cbse and bseb board exams and for other entrance exams
#Link of objective question is below the notes Solutions Class 12 short Notes Chemistry Chapter 2 for quick revision 1. A solution is a homogeneous mixture of two or 9. more chemically non-reacting substances. The components of a solution generally cannot be separated by filtration, settling or centrifuging. 2. A solution may be classified as solid, liquid or a gaseous solution. 3. Solubility is defined as the amount of solute in a saturated solution per 100g of a solvent. 4. The solubility of a gas in a liquid depends upon (a) the nature of the gas and the nature of the liquid, (b) the temperature of the system, and (c) the pressure of the gas. 5. The effect of pressure on the solubility of a gas in a liquid is governed by Henry’s Law. It states that the solubility of a gas in a liquid at a given temperature in directly proportional to the partial pressure of the gas Mathematically, P = KHX where P is the partial pressure of the gas; and X is the mol...
