Paramagnetism method is not used for the composition determination of ______________ in gases?
Correct answer: B. Carbon dioxide
- A. Oxygen
- B. Carbon dioxide
- C. Oxides of nitrogen
- D. Any of these
Explanation
Paramagnetic gas analysis is suitable for oxygen and nitrogen oxides because they exhibit paramagnetism. Carbon dioxide is diamagnetic, so it cannot be determined by this method.
