Question
In van Arkel method, if I2 is introduced at 1700 K over impure metal, the product will be :
Answer: A
💡 Solution & Explanation
Step 1: Check the processes: van Arkel method is used for Zirconium; Kroll's process is used for Titanium; distillation is used for volatile Zinc. Step 2: Froth floatation is used for sulfide ores. Cerussite (PbCO3) is a carbonate ore of lead. Step 3: Since carbonate ores are not concentrated by froth floatation, the pair 'Froth Floatation - Cerussite' is incorrectly matched, which corresponds to option (c).
