Give one example of an electrolytic decomposition reaction used in metallurgy.

Explanation

### Step-by-Step Text Solution:

1. **Understanding Electrolytic Decomposition Reaction**:
- An electrolytic decomposition reaction involves breaking down a compound into its constituent elements or simpler compounds using electricity. This process is known as electrolysis.

2. **Identifying the Electrolyte**:
- In metallurgy, we often use compounds that can be decomposed through electrolysis. One common example is sodium chloride (NaCl), which is also known as table salt.
