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

Here are some questions that are associated with Oxidizing & Reducing Agents:
