Question
Chromium is obtained by reducing concentrated chromite ore with:
Answer: C
💡 Solution & Explanation
Step 1: Chromite ore is processed to obtain chromium(III) oxide (Cr2O3). Step 2: Chromium is extracted by the reduction of Cr2O3 via the alumino-thermite process: Cr2O3 + 2Al -> Al2O3 + 2Cr. Step 3: Therefore, aluminium powder is used as the reducing agent, which corresponds to option (c).
