Answer

To determine the gases liberated at the anode during the electrolysis of aqueous sodium acetate (CH3COONa), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electrolysis**: Electrolysis is a chemical process that uses electricity to drive a non-spontaneous reaction. In this case, we are looking at the electrolysis of sodium acetate in an aqueous solution.

2. **Chemical Composition**: Sodium acetate (CH3COONa) dissociates in water to form sodium ions (Na⁺) and acetate ions (CH3COO⁻).

3. **Oxidation and Reduction**: During electrolysis, oxidation occurs at the anode (positive electrode) and reduction occurs at the cathode (negative electrode). We need to focus on the anode for this question.

4. **Anode Reaction**: At the anode, the acetate ions (CH3COO⁻) can undergo oxidation. The oxidation of acetate can lead to the formation of ethane (C2H6) and carbon dioxide (CO2). The overall reaction can be summarized as:
\[ 2 \text{CH}_3\text{COO}^- \rightarrow \text{C}_2\text{H}_6 + 2 \text{CO}_2 + \text{NaOH} \]

5. **Identifying Gases**: From the reaction, we can see that the gases produced at the anode are:
- Ethane (C2H6)
- Carbon dioxide (CO2)

6. **Conclusion**: Therefore, the gases liberated at the anode during the electrolysis of aqueous sodium acetate are ethane (C2H6) and carbon dioxide (CO2).

### Final Answer:
The gases liberated at the anode in the electrolysis of aqueous sodium acetate are ethane (C2H6) and carbon dioxide (CO2).
