The Amazing World of Solutes, Solvents, and Solutions Extra Questions and Answers for Practice

1. Multiple choice questions.

1. Which of the following is considered a solution?

(a) Sand and water
(b) Salt and water
(c) Sawdust and water
(d) Oil and water

Answer: (b) Salt and water.

2. When more solute can dissolve in a given solution at a certain temperature, the solution is called:

(a) Saturated solution
(b) Unsaturated solution
(c) Dilute solution
(d) Concentrated solution

Answer: (b) Unsaturated solution.

3. The mass per unit volume of a substance is called:

(a) Volume
(b) Weight
(c) Density
(d) Concentration

Answer: (c) Density.

4. The component present in larger quantity in a solution is called:

(a) Solute
(b) Solvent
(c) Mixture
(d) Suspension

Answer: (b) Solvent.

5. Which property allows ice to float on water?

(a) High melting point
(b) Low boiling point
(c) Lower density than liquid water
(d) Transparency

Answer: (c) Lower density than liquid water.

2. Very Short Answer (VSA).

1. Define solubility.

Answer: Solubility is the maximum amount of solute that can be dissolved in a fixed quantity of solvent at a particular temperature.

2. What is a saturated solution?

Answer: A saturated solution is one in which no more solute can be dissolved at a specific temperature.

3. What is a solute?

Answer: A solute is the substance that dissolves in a solvent to form a solution.

4. Identify the solvent in air.

Answer: The solvent in air is nitrogen, because it is present in the largest amount.

5. State the formula for density.

Answer: Density = Mass / Volume.

3. Short Answer Questions.

1. Explain why all sips of homemade ORS taste the same.

Answer: Homemade ORS tastes the same in every sip because sugar and salt are dissolved evenly in water, forming a uniform solution. This even distribution ensures each part of the solution has the same taste and concentration.

2. Describe the effect of temperature on the solubility of baking soda in water, as observed during an experiment.

Answer: As temperature increases, the solubility of baking soda in water also increases. More baking soda dissolves at higher temperatures (like 50°C or 70°C), whereas less dissolves at lower temperatures such as 20°C.

3. State why measuring cylinders are designed tall and narrow rather than short and wide like beakers.

Answer: Measuring cylinders are tall and narrow to allow accurate measurement of liquid volumes. This shape helps in reading the lowest point of the meniscus clearly, improving precision.

4. Give one reason why aquatic life survives better in cold water compared to warm water.

Answer: Cold water can dissolve more oxygen than warm water, so aquatic organisms get more dissolved oxygen in cold water, which is vital for their survival.

5. How can you measure the volume of an irregular-shaped object like a stone?

Answer: Measure the initial volume of water in a measuring cylinder, add the stone, and record the new volume. The difference shows the stone's volume using the water displacement method.

4. True or False Questions.

1. Sugar and salt dissolve in oil just like in water.

Answer: False.

2. The solution obtained by mixing sand in water is uniform.

Answer: False.

3. Air is a solution of different gases.

Answer: True.

4. In liquids, the solubility of gases decreases as temperature increases.

Answer: True.

5. The density of a substance depends on its shape.

Answer: False.

3. Fill in the Blanks Questions.

1. When salt is added to water and dissolves completely, salt is the _______, water is the _______, and the result is a _______.

Answer: solute, solvent, solution

2. The maximum quantity of a solute that can dissolve in a fixed amount of solvent at a given temperature is called its _______.

Answer: solubility

3. The curved surface formed by a liquid in a measuring cylinder is called the _______.

Answer: meniscus

4. The density of a substance is calculated as _______ divided by _______.

Answer: mass, volume

5. A solution that still allows more solute to be dissolved at a given temperature is called _______ solution.

Answer: unsaturated
