Sample questions

1. Which of the following is an example of a homogeneous solution?

   1. Sand in water
   2. Oil in water
   3. Salt in water
   4. Mud in water
   Show answer

   Answer: C. Salt in water

   A homogeneous solution has a uniform composition throughout. Salt dissolves completely in water, resulting in a uniform mixture.

2. Identify the type of solution where the solute is a solid and the solvent is a liquid.

   1. Gas in liquid
   2. Liquid in liquid
   3. Solid in liquid
   4. Gas in solid
   Show answer

   Answer: C. Solid in liquid

   This is the basic definition of a solid dissolved in a liquid.

3. Describe an alloy and classify it as a type of solution.

   1. A homogeneous mixture of metals.
   2. A heterogeneous mixture of metals.
   3. A mixture of non-metals
   4. A pure substance.
   Show answer

   Answer: A. A homogeneous mixture of metals.

   Alloys are homogeneous solid solutions of two or more metals.

4. Discuss the factors affecting the rate of dissolution of a solid in a liquid.

   1. Only temperature matters.
   2. Only surface area matters.
   3. Temperature, surface area, and stirring matter.
   4. Only stirring matters.
   Show answer

   Answer: C. Temperature, surface area, and stirring matter.

   Increased temperature, greater surface area, and stirring all increase the rate of dissolution.

5. Elaborate on the concept of colligative properties and give examples. Explain why these properties depend only on the number of solute particles and not their identity.

   1. Colligative properties depend on the identity of the solute particles.
   2. Colligative properties only depend on the nature of the solvent.
   3. Colligative properties depend on the number of solute particles and their identity.
   4. Colligative properties depend only on the number of solute particles, not their identity because they are based on the disruption of solvent-solvent interactions.
   Show answer

   Answer: D. Colligative properties depend only on the number of solute particles, not their identity because they are based on the disruption of solvent-solvent interactions.

   Colligative properties (like boiling point elevation, freezing point depression) depend only on the number of solute particles, irrespective of their nature. This is because they are based on the disruption of solvent-solvent interactions.
