The element which is recovered from electrolytic process is: — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Step 1: Highly electropositive metals (like Aluminium, Sodium, Potassium, Magnesium) have very high negative reduction potentials and cannot be easily reduced by chemical reducing agents like carbon or carbon monoxide. Step 2: Consequently, these reactive metals must be extracted via the electrolytic reduction of their fused salts or oxides (e.g., the Hall-Heroult electrolytic process for alumina). Step 3: Therefore, among the given metals, aluminium is commercially recovered by an electrolytic process, which corresponds to option (c).
