Class 9th Chemistry Chapter 6 Exercise MCQs, Short Questions And Long Questions

Solutions play a pivotal role in understanding the chemistry of everyday life. In Chapter 6 of Class 9th Chemistry, students dive into the detailed world of solutions, exploring their properties, types, and significance.

This article provides comprehensive notes covering exercise MCQs, short questions, and long questions to ensure students grasp the concepts effectively and excel in exams.

What Is Covered in These Notes?

These notes focus on the critical concepts of solutions, including:

• Multiple Choice Questions (MCQs): Designed to test core concepts and real-life applications of solutions.
• Short Questions: Concise explanations for quick revisions.
• Long Questions: Detailed answers for in-depth understanding.

Key topics include:

• Properties of solutions.
• Differentiation between dilute and concentrated solutions.
• Preparation of supersaturated and saturated solutions.

Exercise MCQs, Short Questions, and Long Questions

This section includes curated practice questions to reinforce the understanding of solutions.

Multiple Choice Questions:

1. Mist is an example of which type of solution?
   • (A) Liquid in gas
   • (B) Gas in liquid
   • (C) Solid in gas
   • (D) Gas in solid
   (Correct Answer: A)
2. A 5% (w/w) sugar solution means:
   • (A) 5 g of sugar dissolved in 90 g of water.
   • (B) 5 g of sugar dissolved in 100 g of water.
   • (C) 5 g of sugar dissolved in 95 g of water.
   • (D) 5 g of sugar dissolved in 105 g of water.
   (Correct Answer: C)

Short Questions:

1. Differentiate between dilute and concentrated solutions with examples.
   • Dilute Solution: Contains a small amount of dissolved solute, e.g., 0.1M NaCl solution.
   • Concentrated Solution: Contains a large amount of solute, e.g., 5M NaCl solution.
2. How can we test whether a given solution is colloidal?
   • Shine a light through the solution. If the light beam scatters, it is a colloid (Tyndall effect).

Long Questions:

1. Explain the preparation and properties of saturated solutions with examples.
   • Saturated solutions contain the maximum amount of solute at a given temperature. E.g., a saturated NaCl solution at room temperature dissolves no additional NaCl.

Tool for Success in Exams
