When chlorine gas (Cl₂) is bubbled through an iron(II) sulphate (FeSO₄) solution, a series of chemical reactions occur. Here's an explanation of what happens at each step.
1. Formation of Iron(II) Chloride:
Chlorine gas (Cl₂) reacts with water (H₂O) in the solution to produce hydrochloric acid (HCl) and hypochlorous acid (HClO). The hypochlorous acid further reacts with iron(II) sulphate to form iron(II) chloride (FeCl₂), water, and sulphuric acid (H₂SO₄).
2 H₂O + Cl₂ → 2 HCl + HClO
HClO + FeSO₄ → FeCl₂ + H₂SO₄
2. Oxidation of Iron(II) Chloride to Iron(III) Chloride:
Iron(II) chloride is unstable in the presence of chlorine gas. It gets oxidized to form iron(III) chloride (FeCl₃) and chlorine gas.
2 FeCl₂ + Cl₂ → 2 FeCl₃
Overall, the reaction can be represented as:
FeSO₄ + Cl₂ → FeCl₃ + H₂SO₄
In summary, when chlorine is bubbled through iron(II) sulphate solution, it reacts to form iron(II) chloride and then gets further oxidized to form iron(III) chloride along with the formation of sulfuric acid.
