| 1. Some more examples of redox reaction are as follows. Identify the reductants and oxidants from them. 2H2S + SO2 ⟶ 3S↓ + 2H2O ... (27) MnO2 + 4 HCl ⟶ MnCl2 + 2H2O + Cl2 ↑ ... (28) |

|---|---|---|---|---|---|---|---|---|---|
→ The oxidants and reductants are:

| 2. If oxidation means losing electrons, what is meant by reduction? | |||||||||
| → Reduction means gaining electron(s). 1 Mark |

| 3. Write the reaction of formation of Fe2+ by reduction Fe3+ by making use of the symbol (e-). | |||||||||
| → Fe3+ + e- ⟶ Fe2+1 Mark |
