FAQs on Solutions Mock Test 1-2 for JEE Main 2025-26: Comprehensive Practice & Expert Solutions
1. What is a solution in chemistry?
A solution is a homogeneous mixture composed of two or more substances. The substance present in a larger amount is called the solvent, while the one dissolved is termed the solute. Solutions have uniform composition and properties throughout.
2. What are the types of solutions based on physical states?
Solutions are classified according to the physical states of their components: solid solutions (e.g., alloys), liquid solutions (e.g., salt in water), and gaseous solutions (e.g., air). Each type demonstrates the uniform dispersion of solute within the solvent.
3. How does temperature affect the solubility of solutes?
The solubility of solids in liquids generally increases with temperature, while that of gases in liquids typically decreases. This is because higher temperature increases the kinetic energy of particles, allowing most solids to dissolve more, but decreases gas solubility due to greater tendency to escape the liquid phase.
4. What is concentration of a solution and how is it expressed?
Concentration refers to the amount of solute present in a given quantity of solvent or solution. Key expressions include molarity (mol/L), molality (mol/kg), mass percentage, and volume percentage. Each method suits different experimental requirements.
5. What is Henry’s Law and its applications?
Henry’s Law states that the amount of gas dissolved in a liquid is directly proportional to its partial pressure above the liquid, at a constant temperature. This principle is important for bottled drinks carbonation and understanding scuba diving risks like decompression sickness.
6. What is the difference between an ideal and a non-ideal solution?
An ideal solution obeys Raoult’s Law at all concentrations and shows no change in enthalpy or volume on mixing. Non-ideal solutions deviate from Raoult's Law due to attractive or repulsive forces between different molecules, leading to positive or negative deviations.
7. What are colligative properties? Name them.
Colligative properties depend only on the number of solute particles in a solution, not on their nature. The main types include: relative lowering of vapour pressure, elevation of boiling point, depression of freezing point, and osmotic pressure.
8. How do you solve numericals based on molarity and molality?
To solve molarity questions, use the formula: Molarity (M) = moles of solute / volume of solution in litres. For molality: Molality (m) = moles of solute / mass of solvent in kg. Carefully convert units when required and use appropriate values from the question statement.
9. What factors affect the solubility of a substance?
The solubility of a solute is affected by: nature of solute and solvent, temperature, pressure (for gases), and the presence of other substances or impurities. These factors can either increase or decrease the amount of solute that dissolves.
10. What is Raoult’s Law?
Raoult’s Law states that the partial vapour pressure of each component in a solution is proportional to its mole fraction and the vapour pressure of the pure component. This law is strictly applicable to ideal solutions.
11. How is the concept of solutions tested in JEE Main and CUET exams?
In JEE Main and CUET exams, the solutions chapter is tested through numerical as well as conceptual questions covering molality, molarity, colligative properties, vapor pressure, and ideal/non-ideal solutions. Practice with NCERT problems, previous year questions, and mock tests helps in mastering the concepts.
12. What should you focus on while solving mock tests for the solutions chapter?
While attempting solutions mock tests, focus on: unit conversions, understanding concepts of solubility and concentration, clear step-by-step problem solving, identifying common mistakes, and time management. Regular practice improves accuracy and boosts your confidence for actual exams.
