The noble gases can be separated by: — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: The separation of noble gases from a mixture is historically performed using Dewar's coconut charcoal method. Step 2: This method exploits the difference in the extent of physical adsorption of different noble gases on activated coconut charcoal at different temperatures. Step 3: Gases are selectively adsorbed and then desorbed by varying the temperature of the charcoal. Thus, option (c) is the correct choice.
