A mixture of sulphur and carbon disulphide is

Options

A. heterogeneous and shows Tyndall effect
B. homogeneous and shows Tyndall effect
C. heterogeneous and does not show Tyndall effect
D. homogeneous and does not show Tyndall effect.

Explanation

To determine the nature of a mixture of sulfur and carbon disulfide, we can follow these steps:

### Step 1: Identify the Components
- The mixture consists of sulfur and carbon disulfide (CS₂).

### Step 2: Determine Solubility
- Carbon disulfide is a solvent that can dissolve sulfur. When sulfur is mixed with carbon disulfide, it forms a solution.

### Step 3: Classify the Solution
- Since the sulfur dissolves in carbon disulfide, we need to classify the type of solution formed.

### Step 4: Understand Homogeneous vs. Heterogeneous Mixtures
- A homogeneous mixture has a uniform composition and the particles are evenly distributed throughout the solution. In contrast, a heterogeneous mixture has distinct, separate phases or components.

### Step 5: Analyze the Mixture
- In this case, because sulfur is completely dissolved in carbon disulfide, the mixture has a uniform composition. Thus, it is classified as a homogeneous mixture.

### Step 6: Tyndall Effect
- The Tyndall effect refers to the scattering of light by particles in a colloidal solution. Homogeneous mixtures do not exhibit the Tyndall effect because they do not have larger particles that can scatter light.

### Step 7: Conclusion
- Therefore, the mixture of sulfur and carbon disulfide is a homogeneous mixture and does not show the Tyndall effect.

### Final Answer
- A mixture of sulfur and carbon disulfide is a **homogeneous mixture** and **does not show the Tyndall effect**.
