Question

state and explain observation that will be made if a sample of sulphur is heated with concentrated nitric V acid

Answer 1

End valency for oxidation 6.

Concentrated nitric acid acts as an oxidizing agent for both sulfur & carbon. In the case of sulfur, S will get the oxygen atoms & the water needed for the reaction: S+6HNO3→H

2

SO

4

+2H

2

O+6NO

2

so if sulfur is converted to SO

2

first, it will proceed into SO

3

& eventually to H
