Can $PCl_{5}$ act as an oxidizing as well as a reducing agent? Justify.

(N/A) $PCl_{5}$ can only act as an oxidizing agent. The highest oxidation state that $P$ can show is $+5$. In $PCl_{5}$,phosphorus is in its highest oxidation state $(+5)$. Since it cannot increase its oxidation state further,it cannot act as a reducing agent. However,it can decrease its oxidation state by gaining electrons and thus act as an oxidizing agent.
