Substances that can act as oxidising agents:
An oxidising agent is a substance that accepts electrons from another substance during a redox reaction. The oxidising agent itself gets reduced while causing the other substance to oxidise. The following are the substances that can act as oxidising agents:
Substances having high electronagavity:
A substance with high electronagavity attracts electrons towards itself. Such substances have a strong tendency to gain electrons and thus act as oxidising agents. For example, fluorine, chlorine, and oxygen are highly electronegative and readily accept electrons, thereby oxidising other substances.
Substances having low ionisation potential:
A substance with low ionisation potential is one that can easily lose valence electrons. Such substances have a tendency to lose electrons and act as reducing agents. However, if the same substance is in the presence of an oxidising agent, it can lose electrons and act as an oxidising agent itself.
Substances having high electropositivity:
A substance with high electropositivity readily loses electrons and becomes positively charged. Such substances have a tendency to donate electrons and act as reducing agents. However, if the same substance is in the presence of an oxidising agent, it can lose electrons and act as an oxidising agent itself.
Conclusion:
In conclusion, a substance that acts as an oxidising agent has a strong tendency to accept electrons and get reduced. Such substances include those with high electronagavity, low ionisation potential, and high electropositivity.
