Good afternoon, I'm very confused.

I'm trying to isolate nitrogen

I put powdered iron into the pipes, and that tube bubbled into hydrochloric acid and mixed sodium chloride, the clear solution turned green? how did the air send, how did the compressor turn off, the solution became transparent again?

  what happened??
