Question

Give balanced chemical equations for the following reactions: 
(i) Fluorine treated with a dilute sodium hydroxide solution.
(ii) Hydrogen sulphide treated with concentrated sulphuric acid.
(iii) Potassium iodide treated with acidified potassium pennanganate solution. 

Answer 1

(i) 2F₂ + 2NaOH → 2NaF + H₂O +OF₂

(ii)   `H_2S + underset(conc.) (H_2SO_4) → S+SO_2 + 2H_2O`

(iii) 2KMnO₄ + 8H₂SO₄ + 10KI → 6K₂SO₄ +2MnSO₄ + 8H₂O +5I₂
