In Dumas method for the estimation of \(N _2\), the sample is heated with copper oxide and the gas evolved is passed over :
- A \(Ni\)
- B Copper gauze
- C \(Pd\)
- D Copper oxide
Answer & Solution
Correct Answer
(B) Copper gauze
Step-by-step Solution
Detailed explanation
Duma's method. The nitrogen containing organic compound, when heated with \(CuO\) in a atmosphere of \(CO _2\), yields free \(N _2\) in addition to \(CO _2\) and \(H _2 O\).…
