O Level Chemistry – Oxidizing & Reducing Agents

We shall continue with Oxidizing & Reducing Agents and more questions that were discussed before on “Secrets of Redox & Electrolysis”.

A reducing agent is a substance that reduces another substance by:

• giving hydrogen to the substance
• removing oxygen from the substance
• giving electrons to the substance

In the process of reducing another substance, the reducing agent itself becomes oxidized.

Common Reducing Agents are:

• Potassium Iodide, KI
• Reactive Metals such as Mg, Zn
• Hydrogen Gas, H2
• etc

while

An oxidizing agent is a substance that oxidizes another substance by

• giving oxygen to the substance
• removing hydrogen from the substance
• receiving electrons to the substance

In the process of oxidizing another substance, the oxidizing agent itself becomes reduced.

Common Oxidizing Agents are:

• Acidified Potassium Manganate (VII), KMnO4 (purple solution)
• Acidified Potassium Dichromate (VI), K2CrO7 (orange solution)
• Halogens e.g. Cl2 gas, Chlorine water
• etc
