Answer

To solve the question regarding the type of colloid formed when a metal is in the form of a dispersed phase and water is the dispersion medium, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components**:
- The dispersed phase is the metal.
- The dispersion medium is water.

2. **Understand Colloids**:
- A colloid consists of two main components: the dispersed phase and the dispersion medium.

3. **Classify the Colloid**:
- Since the dispersion medium is water, we need to determine the nature of the interaction between the metal (dispersed phase) and water (dispersion medium).
- Metals typically do not have a strong attraction to water.

4. **Determine the Type of Colloid**:
- When the dispersed phase (metal) does not interact favorably with the dispersion medium (water), the colloid formed is classified as a hydrophobic colloid.
- Hydrophobic colloids are characterized by a lack of attraction between the dispersed phase and the dispersion medium, leading to instability.

5. **Conclusion**:
- Therefore, the colloid formed when a metal is the dispersed phase and water is the dispersion medium is termed a **hydrophobic colloid**.

### Final Answer:
The colloid is termed as **hydrophobic colloid**.
