(a) Identify the reducing agent in the following reactions :
(i) 4NH3 + 5O2 → 4NO + 6H2O
(ii) H2O + F2 → HF + HOF
(iii) Fe2O3 + 3CO → 2Fe + 3CO2
(iv) 2H2 + O2 → 2H2O
(b) Define a redox reaction in terms of gain or loss of oxygen.
Solution
(a) (i) NH3
(ii) H2O
(iii) CO
(iv) H2
(Award full mark if part (ii) of (a) is attempted)
(b) A reaction in which the gain or loss of oxygen takes place simultaneously is called a redox reaction.
