Answer 2

QUESTION

What happens when dilute hydrochloric acid is added to iron fillings ?

ANSWER

When dilute Hydrochloric acid is added to iron filings, iron chloride & hydrogen gas is produced.

$Fe+2HCl⟶FeCl2+H2$

The iron displaces hydrogen from hydrochloric acid to form iron (II) chloride & hydrogen gas. This is a single displacement reaction.

Let us consider the reaction between acid and metal

Acid + Metal → Salt + Hydrogen gas (H2)

in this case

Acid = Dilute HCl

Metal = Iron (Fe)

∴ HCl + Fe → FeCl2 + H2

Let us balance the equation,

2HCl + Fe → FeCl2 + H2

when dilute HCl is added to Fe then Ferrous chloride (FeCl2) and hydrogen gas (H2) will be formed.
