Book Free Demo1. Identify the reducing agent in the following reactions.
2H_2 + O_2 → 2H_2O
A reducing agent is an element that undergoes (becomes oxidised).
2H_2 + O_2 → 2H_2O
In the above reaction, hydrogen 2H_2 is oxidized to water 2H_2O by gaining an oxygen atom. Hence, hydrogen 2H_2 is a as it undergoes oxidation.
2. Identify the oxidising agent (oxidant) in the following reaction.
3Fe + 4H_2O → Fe_3O_4 + 4H_2
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 reduced.
3Fe + 4H_2O → Fe_3O_4 + 4H_2
In the above reaction, water (H_2O) is the ; it oxidises iron (Fe) to form iron(III) oxide (Fe_3O_4) and hydrogen (H_2).
