Question:
Identify the redox reactions out of the following reactions and identify the oxidising and reducing agents in them.
(i) 3HCI(aq) + HNO3 (aq) → CI2(g) + NOCI (g) + 2H2O(l)
(ii) HgCI2 (aq) + 2KI (aq) → HgI2 (s) + 2KCI (aq)
(iii) Fe2O3 (s) + 3CO(g) → 2Fe (s) + 3CO2(g)
(iv) PCI3 (I) + 3H2O (I) → 3HCI (aq) + H3 Po3 (aq)
