WHAT ARE REDUCING AGENTS OXIDISING AGENTS - EASY ANALYSIS

 

 WHAT ARE REDUCING AGENTS OXIDISING AGENTS - EASY ANALYSIS

 

 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 oxidised.

Common Reducing Agents are:

  • Potassium iodide, KI (colourless solution)
  • Reactive metals such as Mg, Zn, Al
  • Hydrogen gas, H2
  • Carbon, C
  • Carbon monoxide, CO
  • Hydrogen sulfide, H2S
  • Sulfur dioxide, SO2

Test for Oxidising Agent: Use of a Reducing Agent e.g. aqueous potassium iodide, KI(aq)  Observation: Colourless solution turns brown.

Chemistry behind it: 2I(aq) => I2(aq) + 2e

******************************************************************************************************

An oxidising agent is a substance that oxidises another substance by

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

In the process of oxidising another substance, the oxidising agent itself becomes reduced

Common Oxidising Agents are:

  • Acidified potassium manganate (VII), KMnO4 (purple solution)
  • Acidified potassium dichromate (VI), K2Cr2O7 (orange solution)
  • Halogens e.g. Cl2, Br2
  • Concentrated Sulfuric acid, H2SO4
  • Nitric acid, HNO3
  • Oxygen, O2

Test for Reducing Agent: Use of an Oxidising Agent e.g. acidified potassium manganate (VII). Observation: Purple solution decolourises.

Chemistry behind it: MnO4(aq) + 8H+(aq) + 5e– => Mn2+(aq) + 4H2O(l)
