Answer to Question #154718 in General Chemistry for Benjamin Busuulwa

Question

outline The industrial preparation of sulphuric acid from zinc sulphide(use equations only)

Answer 1

Preparation of sulphuric acid from zinc sulphide

ZnS + $\frac{3}{2}$ O₂ $\to$ ZnO + SO₂

2SO₂ + O₂ $\to$ 2 SO₃ ( reaction in the presence of V₂O₅ at 450⁰C )

SO₃ + H₂SO₄ (conc.) $\to$ H₂S₂O₇ (oleum)

H₂S₂O₇ + H₂O $\to$ 2H₂SO₄ (sulphuric acid)
