In the electrolytic refining of a metal M, what would you take as the anode, the cathode and the electrolyte?

Explanation

**Step-by-Step Solution:**

1. **Identify the Metal M**: In the electrolytic refining process, we start with a metal M that contains impurities. The goal is to purify this metal.

2. **Set Up the Electrolytic Cell**: The electrolytic refining involves an electrolytic cell, which consists of two electrodes (anode and cathode) and an electrolyte.

3. **Select the Anode**: The anode is made of the impure metal M. This is where the oxidation reaction occurs, and the metal will dissolve into the electrolyte.
