It could be iron metal.........

Explanation:

And how would you know? Add some dilute hydrochloric acid to iron filings.......

"iron + hydrochloric acid "rarr" iron chloride + dihydrogen gas"iron + hydrochloric acid iron chloride + dihydrogen gas

Fe(s) + 2HCl(aq) rarr FeCl_2(aq) + H_2(g)uarrFe(s)+2HCl(aq)FeCl2(aq)+H2(g)

In water, FeCl_2(aq)FeCl2(aq), is probably the pale green [FeCl_2((OH)_2)_4][FeCl2((OH)2)4] complex.
