Which oxide of nitrogen is used in chloroform solution? A. Nitric oxide B. Nitrogen dioxide C. Nitrous oxide D. Nitrogen Pentoxide Correct Answer D
The correct answer is Nitrogen Pentoxide.
Key Points
- Nitrogen pentoxide is produced by dehydration of nitric acid by phosphorus Pentoxide.
- Nitrogen pentoxide, Molecular weight is 108.02.
- The Pentoxide Molecular formula is N2O5.
- The boiling point of Pentoxide is 47.0°C & the Melting point 30°C.
- Pentoxide is Sublimes at -32.4°C but undergoes moderately rapid decomposition into 02 and the NO2/N204.
- Equilibrium mixture at temperatures above -10°C. Freely soluble in chloroform without appreciable decomposition.
Important Points
- Nitric oxide Burns when heated with hydrogen. It combines with oxygen to
form nitrogen dioxide and with halogens to form nitrosyl halides, Ex. NOC. - Nitrous oxide supports combustion. Very stable and rather inert chemically at room temperatures. Dissociation begins above 300°C when the gas becomes a strong oxidizing agent.
- Nitrogen dioxide It has an irritating odour and is highly poisonous. Under normal atmospheric conditions, it exists in equilibrium with nitrogen tetroxide (N204) Heavier than air. Nitrogen dioxide produces nitrous acid (HN02) and nitric acid (HN03) on contact with water.
