What metal when reacted with dilute hydrochloric acid, gives a pale green solution?

1 Answer

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

Explanation:

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

$iron + hydrochloric acid \to iron chloride + dihydrogen gas$ $"iron + hydrochloric acid "rarr" iron chloride + dihydrogen gas"$

$F e (s) + 2 H C l (a q) \to F e C l_{2} (a q) + H_{2} (g) ↑ ⏐$ $Fe(s) + 2HCl(aq) rarr FeCl_2(aq) + H_2(g)uarr$

In water, $F e C l_{2} (a q)$ $FeCl_2(aq)$ , is probably the pale green $[F e C l_{2} {({(O H)}_{2})}_{4}]$ $[FeCl_2((OH)_2)_4]$ complex.
