Can PCl_(4) acts as an oxidising as well as a reducing agent? Justify. |
| Answer» Solution :Oxidation state of P in `PCl_(5)` is `+5`. Since P has five valence electrons in its valence shell, THEREFORE, it cannot increase its oxidation state BEYOND `+5` by donating its electrons therefore `PCl_(5)` cannot act as a REDUCING agent. HOWEVER, it can decrease its oxidation number from `+5` to `+3` or some lower value, therefore `PCl_(5)` acts as an oxidising agent. For example, it oxidises Ag to AgCl. | |
