1. Identify the reducing agent in the following reactions.
\(Fe_2O_3\) + \(3CO\) → \(2Fe\) + \(3CO_2\)
A reducing agent (reductant) is a substance that reduces another substance (by removing oxygen or adding hydrogen) while also being oxidised.
\(Fe_2O_3\) + \(3CO\) → \(2Fe\) + \(3CO_2\)
In the above reaction, carbon monoxide is oxidized to carbon dioxide by gaining an oxygen atom. Hence, is a reducing agent as it undergoes .
2. Identify the oxidising agent (oxidant) in the following reaction.
\(V_2O_5\) + \(5Ca\) → \(2V\) + \(5CaO\)
An oxidising agent (oxidant) is a substance that another substance (by losing electrons or removing hydrogen or adding oxygen, or increasing oxidation state) while also being .
\(V_2O_5\) + \(5Ca\) → \(2V\) + \(5CaO\)
\(V_2O_5\) is an oxidising agent as it oxidises \(Ca\) to \(CaO\).
