Question 35

Nitrogen and its Compounds

A pair of compounds that can be used to generate a gas which has physiological effect on human beings is

  1. A.sodium trioxonitrate (V) and calcium chloride
  2. B.sodium dioxonitrate (III) and ammonium chloride
  3. C.sodium trioxonitrate (V) and ammonium chloride
  4. D.sodium dioxonitrate (III) and potassium chloride.
Show the answer and explanation

Answer: C (sodium trioxonitrate (V) and ammonium chloride)

Explanation

Heating sodium trioxonitrate(V) with ammonium chloride produces ammonium trioxonitrate(V), which decomposes to dinitrogen oxide (laughing gas), an anaesthetic. Option B gives nitrogen, which has no such effect.
