In the experiment above. Z can be
- a solution of sodium dioxonitrate (lll) and ammonium chloride
- a solution of lead trioxnitrate (V)
-
a solution of sodium trioxonitrate (V) and ammonium chloride
- concentrated tetraoxosulphate (VI) acid and sodium trioxonitrate (V)
The correct answer is: C
Explanation
Nitrogen(I) oxide(laughing gas) can be prepared in the laboratory by the action of heat on a mixture of sodium trioxonitrate (V) and ammonium chloride, this colourless gas is collected over water.
