When HCl is added to iron filling then chlorine of HCl reacts with iron by evolving hydrogen gas. The iron dissolves, releasing hydrogen and making an iron chloride solution.
Fe + 2HCl → FeCl₂ + H₂ or
2Fe + 6HCl → 2FeCl₃ + 3H₂
-FeCl₂ is a greenish solution.

What happens on adding dilute HCl to a mixture of iron filling and sul...
When dilute hydrochloric acid (HCl) is added to a mixture of iron filings and sulfur powder, the following reactions occur:

1. Formation of Hydrogen Gas:
Fe(s) + 2HCl(aq) → FeCl2(aq) + H2(g)

The acid reacts with the iron filings to form iron(II) chloride (FeCl2) and hydrogen gas (H2). The hydrogen gas is colorless and odorless.

2. Formation of Iron(II) Chloride:
Fe(s) + 2HCl(aq) → FeCl2(aq) + H2(g)

The acid also reacts with the iron filings to form iron(II) chloride. Iron(II) chloride is a greenish solution, so a greenish solution appears in the reaction mixture. This is the correct answer option (C).

3. Formation of Iron(II) Sulfide:
Fe(s) + S(s) → FeS(s)

The sulfur powder reacts with the iron filings to form iron(II) sulfide (FeS). Iron(II) sulfide is a black solid. This reaction does not occur when dilute HCl is added to the mixture, as the acid does not directly react with sulfur. Therefore, option (D) is not correct.

4. Formation of Hydrogen Sulfide Gas:
H2S(g) + 2HCl(aq) → 2H2O(l) + 2Cl(aq)

If there is any water present in the reaction mixture, the hydrogen sulfide gas (H2S) can react with the acid to form water and chloride ions. However, this reaction is not directly related to the addition of dilute HCl to the mixture of iron filings and sulfur powder. Therefore, option (A) is not correct.

In conclusion, when dilute HCl is added to a mixture of iron filings and sulfur powder, a greenish solution appears due to the formation of iron(II) chloride. Additionally, hydrogen gas is also formed. Therefore, the correct answer is option (C).
