Oxidation-reduction (redox) reactions
What is a redox reaction?
An example and important terms
If this is a redox reaction, what is being reduced and oxidized? What is the reducing agent in this reaction?
What is the oxidizing agent in this reaction?
Based on the title of this article, we can make an educated guess about the first part of this question. Yes, this is probably a redox reaction, but how do we know that for sure? We need to show there is an electron transfer occurring, and we can do that by checking if any oxidation numbers change from the reactants to the products.
Carbon being oxidized because it is losing electrons as the oxidation number increases from to .
Iron is being reduced because it is gaining electrons when the oxidation number decreases from to .
The reducing agent is the reactant that is being oxidized (and thus causing something else to be reduced), so is the reducing agent.
The oxidizing agent is reactant that is being reduced (and thus causing something else to be oxidized), so is the oxidizing agent.
