Question

Acetylene is thermodynamically unstable and readily explodes, therefore it is stored in commercial cylinders used for an oxy-acetylene torch for welding. These cylinders contain:

• A. pumice stone saturated with acetone
• B. charcoal powder saturated with acetone
• C. dissolved in water to give 0.5 M solution
• D. dissolved in tupentine oil

Answer 1
