Answer:

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

Explanation:

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

$\text{iron + hydrochloric acid "rarr" iron chloride + dihydrogen gas}$

$F e \left(s\right) + 2 H C l \left(a q\right) \rightarrow F e C {l}_{2} \left(a q\right) + {H}_{2} \left(g\right) \uparrow$

In water, $F e C {l}_{2} \left(a q\right)$, is probably the pale green $\left[F e C {l}_{2} {\left({\left(O H\right)}_{2}\right)}_{4}\right]$ complex.
