FAQs on JEE Main 2025-26 Mock Tests: Practice, Analyze & Improve
1. What are solutions in chemistry?
A solution is a homogeneous mixture of two or more substances in which the solute is evenly distributed within the solvent. The major component is called the solvent (usually present in a larger amount), and the minor component is the solute. For example, in a saltwater solution, salt is the solute and water is the solvent.
2. What is the difference between a solution, a suspension, and a colloid?
Solution: Homogeneous, particle size < 1 nm, particles do not settle.
Suspension: Heterogeneous, particle size > 1000 nm, particles settle on standing.
Colloid: Intermediate characteristics, particle size between 1 nm and 1000 nm, particles do not settle and can scatter light (Tyndall effect).
3. What are the main types of solutions based on the states of solute and solvent?
Solutions can be classified based on the physical states of their solute and solvent as follows:
1. Solid in liquid (e.g., sugar in water)
2. Gas in liquid (e.g., oxygen in water)
3. Liquid in liquid (e.g., alcohol in water)
4. Solid in solid (e.g., alloys like brass)
4. How is the concentration of a solution expressed?
The concentration of a solution can be expressed in several ways including:
• Mass percentage (w/w)
• Volume percentage (v/v)
• Molarity (mol/L)
• Molality (mol/kg)
• Normality (N)
All these provide different methods for quantifying the amount of solute in a given quantity of solution or solvent.
5. What is the Tyndall effect and how is it observed?
The Tyndall effect is the scattering of light by particles in a colloid or fine suspension. A true solution does not show the Tyndall effect, but a colloidal solution does. When a beam of light passes through a colloidal solution, the path becomes visible due to scattering by the dispersed particles.
6. What is solubility and what factors affect it?
Solubility is the maximum amount of solute that can dissolve in a fixed amount of solvent at a specific temperature and pressure. Factors affecting solubility include:
- Nature of solute and solvent
- Temperature (usually increases for solids in liquids)
- Pressure (affects gases in liquids)
7. What is a saturated and unsaturated solution?
A saturated solution contains the maximum amount of solute that can dissolve at a given temperature. Any additional solute will not dissolve. An unsaturated solution can still dissolve more solute at that temperature.
8. How can the concentration of a solution be increased or decreased?
The concentration of a solution can be increased by:
- Adding more solute
- Evaporating some of the solvent
It can be decreased by:
- Adding more solvent
9. What are the applications of solutions in daily life?
Solutions are present everywhere in daily life. Examples include saltwater for cooking, syrups in medicines, soft drinks, alloys in coins, and air (a gaseous solution). Their use ranges from industrial manufacturing to biological systems.
10. What is a solution architect and what skills are needed for this role?
A solution architect is an IT professional responsible for designing and managing solution architectures for organizations' projects and systems. Key skills include:
- Understanding of cloud platforms and software design
- Expertise in Tally solutions and ERP systems
- Ability to align technical strategies with business goals
11. How are solutions tested in a mock test for JEE Mains or CUET?
In JEE Mains or CUET mock tests, topics like solutions are tested through multiple-choice questions, numerical problems, and assertion-reasoning types. Students are expected to understand properties of solutions, concentration calculations, and application-based scenarios.
12. What are the key concepts students should revise for Solutions chapter before an online test?
Before an online test on solutions, students should revise:
• Types of solutions and differences from mixtures
• Methods of expressing concentration
• Solubility and factors affecting it
• Colloids and properties like Tyndall effect
• Practical applications of solutions in daily life and industry
