Answer:
A. KMnO₄oxidizing agent, FeSO₄ reducing agent
Step-by-step explanation:
In chemical reactions, we have both oxidizing and reducing agents. This chemical reaction is referred to as Redox reaction.
Oxidizing agents or compounds can be defined as compounds that accepts or receives electrons from other compounds and this results in the oxidation of those other compounds. When oxidizing agents accept electrons from other agents, they are reduced. Oxidizing agents are also referred to as electron acceptors.
Reducing agents can be defined as agents or compounds that lose their electrons to other compounds or agents and they reduce those other compounds. When reducing agents lose electrons, they are oxidized in the process. Reducing agents are also called or referred to as electron donors.
In the question, above we were asked to identify the oxidizing and reducing agents.
a) The oxidizing agent in the chemical equation above is KMnO₄(aq). It is an oxidizing agent because in the chemical equation above, it has been reduced to 2MnSO₄(aq).
b) The reducing agent in the chemical equation above is FeSO₄(aq). It is a reducing agent because in the chemical reaction above, it has been oxidized to 5Fe₂(SO4)₃(aq).
