What happen when dilute hydrochloric acid is added to iron filling?

Answered by admin @ 10/08/2021

Hi !

Reaction of acid with metal :-

Acid + Metal ---> Salt + Hydrogen gas

so here ,

acid = hydrochloric acid , HCl
metal = Iron , Fe

HCl + Fe ----> FeCl₂ + H₂ [ unbalanced equation)

balanced equation:-
2HCl + Fe ----> FeCl₂ + H₂

FeCl₂ [ ferric chloride] is the salt produced and H₂ gas is liberated.
