This reaction is a displacement reaction, where iron (Fe) displaces hydrogen (H) in hydrochloric acid (HCl) to form iron(II) chloride (FeCl2) and hydrogen gas (H2).
Single Displacement
The double replacement reaction between FeCl2 and H2S would result in the formation of FeS (iron sulfide) and 2HCl (hydrochloric acid). Iron chloride (FeCl2) reacts with hydrogen sulfide (H2S) to produce iron sulfide (FeS) and hydrochloric acid (HCl) as products.
Iron(II) chloride (FeCl2) can be made by reacting iron with hydrochloric acid (HCl). The reaction produces FeCl2 and hydrogen gas (H2). Another method involves the reaction of iron oxide (FeO) with hydrochloric acid to form FeCl2 and water (H2O). FeCl2 can also be obtained by reducing iron(III) chloride (FeCl3) with hydrogen gas (H2) or with another reducing agent.
Displacement reaction , as HCl displaces S of FeS to give H2S
The reaction between iron and hydrochloric acid can be represented by the following equation: Fe + 2HCl → FeCl2 + H2. This reaction produces iron(II) chloride (FeCl2) and hydrogen gas (H2).

The reaction between FeSO4 (iron(II) sulfate) and BaCl2 (barium chloride) will produce a precipitate of barium sulfate (BaSO4) and iron(II) chloride (FeCl2) in solution. The balanced chemical equation for the reaction is: FeSO4 + BaCl2 -> BaSO4 + FeCl2.
Iron(III) chloride can react with iron or copper and form iron (II) chloride.
In the reaction FeS + 2HCl --> FeCl2+ H2S, the iron replaces the hydrogen and the hydrogen replaces the iron. This is two replacements, so the reaction is a double replacement reaction. (It's sometimes also called a double displacement reaction.)
If you react FeCl2 with soap, the iron ions in FeCl2 are likely to form coordination complexes with the soap molecules. This may not result in any significant chemical reaction, but it could produce colored compounds or a change in the physical properties of the soap.
Very fast corrosion e.g Fe + 2HCl -----> FeCl2 + H2
The mass of of iron(II) chloride (anhydrous) is 633,8 grams.
The equation for the reaction between iron and hydrochloric acid is: Fe(s) + 2HCl(aq) → FeCl2(aq) + H2(g)
