Copper (II) oxide is mixed with organic compound during combustion analysis.The purpose is
Correct answer: A. to carry out complete combustion
- A. to carry out complete combustion
- B. to reduce the economy of the process
- C. to reduce the time for completion of the reaction
- D. all of the above
Explanation
Complete Combustion: Copper (II) oxide serves as an oxidizing agent. In combustion analysis, the organic compound is burned in the presence of excess oxygen provided by copper (II) oxide. This ensures complete combustion of the organic compound, converting all carbon to carbon dioxide and all hydrogen to water.
