Aluminium is extracted from bauxite by the electrolysis of aluminium oxide dissolved in cryolite. Now answer the following question:
Write down the word which correctly completes the following sentence:
"By dissolving aluminium oxide in cryolite a __________ solution is produced. (nonconducting/conducting)"

Explanation

To solve the question, we need to determine the nature of the solution formed when aluminium oxide (Al₂O₃) is dissolved in cryolite (Na₃AlF₆).

### Step-by-Step Solution:

1. **Identify the Components**:
- Aluminium oxide (Al₂O₃) is the primary substance we are considering.
- Cryolite (Na₃AlF₆) is the substance used to dissolve aluminium oxide.
