Introduction
Oxidation takes place when you either add oxygen or remove hydrogen. Reduction is when oxygen is removed and hydrogen is added. Redox reaction is when both reduction and oxidation takes place in the same reaction. In redox reactions, oxidation and reduction both occur at the same time. In redox reactions one reactant gets reduced and the other gets oxidized.
Pre-Requisites:
Reaction, reactants, products
Activity:
Rust forms when Iron reacts with the air in the presence of moisture.
Real Life Question:
How does rust form?
