Question

Canvas Classes · Accepted Answer

An ion acts as an oxidising agent if it can be reduced (i.e., it tends to gain electrons).

Analysis:

| Ion | Tendency | Oxidising agent? |
|---|---|---|
|  | Reduced to  (inert pair effect) | Yes ✓ |
|  | Tends to be oxidised to  | No (reducing agent) |
|  | Stable state, not easily reduced | No |
|  | Reduced to  (inert pair effect) | Yes ✓ |
|  | Reduced to  (inert pair effect) | Yes ✓ |
|  | Stable state | No |

Oxidising agents: , ,  → 3 ions

Answer: Option (1) — 3
