The correct Answer is:
### Step-by-Step Solution 1. **Understanding Adsorption**: Adsorption is the process by which atoms, ions, or molecules from a gas, liquid, or dissolved solid adhere to a surface. The effectiveness of adsorption depends on the surface area of the adsorbent. 2. **Identifying the Adsorbent**: In this case, we are looking for a substance that can adsorb a large volume of hydrogen gas. 3. **Considering Colloidal Solutions**: Colloidal solutions have a very high surface area due to the small size of the particles dispersed in the medium. This high surface area enhances their ability to adsorb gases. 4. **Palladium as an Adsorbent**: Among various substances, palladium is known for its ability to adsorb hydrogen gas. When palladium is in a colloidal form, its surface area is maximized, allowing it to adsorb a larger volume of hydrogen compared to other forms. 5. **Conclusion**: Therefore, the colloidal solution of palladium is the correct answer as it can adsorb a large volume of hydrogen gas due to its high surface area. ### Final Answer The colloidal solution of palladium can adsorb a large volume of hydrogen gas. ---
