High purity copper metal is obtained by : — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Step 1: Crude copper (blister copper) obtained from smelting contains about 2% impurities. Step 2: For electrical applications, very high purity copper is required, which is achieved by electrolytic refining (electrolytic reduction of Cu2+ at the cathode). Step 3: Therefore, high purity copper is obtained by electrolytic reduction, corresponding to option (c).
