When is electrolytic reduction applied for getting a metal?

Explanation

**Step-by-Step Solution:**

1. **Understanding Reduction Processes:**
- Reduction is a chemical process where a substance gains electrons or decreases its oxidation state. There are two main types of reduction: chemical reduction and electrolytic reduction.

2. **Chemical Reduction:**
- Chemical reduction typically involves the use of reducing agents, which donate electrons to the metal ions in their compounds. This method works well for metals that are less reactive.
