Solution is a mixture of solute and solvent. The solution has single phase principle because all the component of the solution have same physical state. Solution depends on concentration, temperature and pressure.

Solid solutions are an allotrope of a chemical compound with more or less than what is considered a typical stoichiometry (ratio). Solid solution is usually formed by mixing two solid components in molten state and then cooling the mixture. Solid solutions can be of two types: substitutional and interstitial solid solutions.

In this chapter, we will learn about: i) Concentration of Solutions ii) Solubility iii) Vapour Pressure of Liquid Solutions iv) Ideal and Non-Ideal Solutions v) Colligative Properties vi) Determination and Abnormal Molar Masses.

Solutions can be broadly categorized into two types: Homogeneous solutions are a mixture of two or more compounds present in a solution at a given temperature and pressure. A homogeneous solution is one which has a uniform composition and properties throughout the solution. The physical properties of a homogeneous solution do not change with variation in the concentration.

No matter what the class is, the syllabus for both class 12 and class 11 is same. Maintaining a balance between proficiency and understanding, we have kept the same level of difficulty in our new class 12th books as we had in our old class 11th books.

Chemistry is all about solving problems and understanding concepts. The NCERT textbooks cover this in minute detail. If you want to score a 100 in chemistry, make sure you don’t skip any chapter. Do make sure to at least try and understand the concepts in the chapter by working out the examples in the book itself.
