A mixture of iodine and carbon tetrachloride is

Options

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

Explanation

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

### Step 1: Identify the Components
- We have two substances: iodine (I2) and carbon tetrachloride (CCl4).

### Step 2: Determine the Type of Mixture
- When iodine is mixed with carbon tetrachloride, we need to assess whether the mixture is homogeneous or heterogeneous.
- A **homogeneous mixture** has a uniform composition throughout, while a **heterogeneous mixture** does not.

### Step 3: Analyze the Solubility
- Iodine is soluble in carbon tetrachloride. When iodine dissolves in carbon tetrachloride, it forms a uniform solution.
- Therefore, the mixture of iodine and carbon tetrachloride is **homogeneous**.

### Step 4: Check for Tyndall Effect
- The Tyndall effect is the scattering of light by particles in a colloid or in very fine suspensions.
- Homogeneous solutions do not exhibit the Tyndall effect because they do not contain large particles that can scatter light.

### Step 5: Conclusion
- Since the mixture of iodine and carbon tetrachloride is homogeneous and does not show the Tyndall effect, the correct answer is:
**Option D: Homogeneous and does not show Tyndall effect.**
