absorbed acetic acid on activated carban is :

Options

A. adsorber
B. absorber
C. adsorbent
D. adsorbate

Answer

To solve the question regarding the absorption of acetic acid on activated carbon, we need to understand the concepts of adsorbent and adsorbate.

### Step-by-Step Solution:

1. **Identify the Components**:
- In the given scenario, we have two main components: acetic acid and activated carbon.

2. **Define Adsorbent and Adsorbate**:
- **Adsorbent**: This is the substance that adsorbs another substance. In this case, activated carbon acts as the adsorbent.
- **Adsorbate**: This is the substance that is being adsorbed onto the surface of the adsorbent. Here, acetic acid is the adsorbate.

3. **Determine the Role of Each Component**:
- Since activated carbon is the material that is capturing or holding the acetic acid molecules on its surface, it is classified as the adsorbent.
- Acetic acid, being the substance that is being held onto the surface of activated carbon, is classified as the adsorbate.

4. **Select the Correct Option**:
- Based on the definitions and roles identified, acetic acid is the adsorbate. Therefore, the correct answer to the question "absorbed acetic acid on activated carbon is:" is option 4, which states that acetic acid is the adsorbate.

### Final Answer:
The absorbed acetic acid on activated carbon is the **adsorbate**.
