Sulphur is an element which exhibits different oxidation numbers in different substances.
(a) In each of the following reactions, indicate whether the sulphur-containing reactant is an oxidizing agent or a
reducing agent. Explain your answers.
2PBS(s) + 302(g) → 2P6O(s) + 2SO2(g)
(i)
(ii) Zn(s) + 2H2SO4(1) → ZnSO4(s) + SO2(g) + 2H;O(1)
(b) In each of the following reactions, indicate whether sulphur undergoes oxidation or reduction. Explain your
answers.
(i)
S(s) + O2(g) → SO2((g)
(ii) S(s) + Fe(s) → FeS(s)
