Please note the substance that undergo oxidation itself and reduce other is called reducing agent whereas the substance that undergo reduction itself and oxidize other is called oxidizing agent. We get to hear the terms like oxidation and reduction a lot in CBSE class 12th Chemistry and to be precise, oxidation means gaining oxygen in a chemical reaction We will be looking at oxidation and reduction from two different points of view. To identify the reduction agent, we must identify the source of the electron. If you're seeing this message, it means we're having trouble loading external resources on our website. So, the conversion of CuO to Cu is reduction reaction. In this quiz you will test out what you know about different compounds and substances and what happens when they undergo this process.
