Which of the following is a homogeneous mixture?

Options

A. Solution of sugar in water
B. Chalk powder in water
C. Kerosene oil in water
D. None of these

Explanation

To determine which of the following is a homogeneous mixture, let's analyze each option step by step.

### Step 1: Understand the Definition of Homogeneous Mixtures
A homogeneous mixture is one in which the components are uniformly distributed, resulting in a consistent composition throughout the mixture. This means that you cannot distinguish the different components with the naked eye.

**Hint:** Remember that in a homogeneous mixture, the composition is uniform and the different substances are not visibly separate.

### Step 2: Analyze the First Option - Solution of Sugar in Water
- When sugar is dissolved in water, it forms a clear solution.
- The sugar particles are uniformly distributed throughout the water.
- Therefore, this is a homogeneous mixture.

**Hint:** Look for solutions where one substance completely dissolves in another, creating a uniform appearance.

### Step 3: Analyze the Second Option - Chalk Powder in Water
- When chalk powder is added to water, it does not dissolve.
- Instead, it forms a suspension where the chalk particles are not uniformly distributed and can settle at the bottom over time.
- Thus, this is a heterogeneous mixture.

**Hint:** If you can see the particles and they settle over time, it is likely a heterogeneous mixture.

### Step 4: Analyze the Third Option - Kerosene Oil in Water
- Kerosene oil does not mix with water; instead, it forms a separate layer on top of the water.
- This indicates that the components are not uniformly distributed.
- Therefore, this is also a heterogeneous mixture.

**Hint:** If two liquids do not mix and form separate layers, it indicates a heterogeneous mixture.

### Conclusion
Based on the analysis:
- The first option, "Solution of sugar in water," is the only homogeneous mixture among the options provided.

**Final Answer:** The correct option is the first one: Solution of sugar in water.
