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"#

#Fe(s) + 2HCl(aq) rarr FeCl_2(aq) + H_2(g)uarr#

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