I/GCSE Chemistry- Oxidation and Reduction

Triple and Double award

· igcse chemistry

In this I/GCSE Chemistry blog post, we will look at the different reactions that occurs in different substances.

OXIDATION

  • Oxidation is defined as the losing of electrons.
  • Any entity that loses electrons has become oxidised in the process. 

REDUCTION

  • Reduction is defined as the gaining of electrons.
  • A redox reaction is when, at the same time, one enity is being reduced whilst another is being oxidised. 

REDUCING AGENTS

  • Tungsten is extracted from its oxide by heating in a stream of hydrogen. 

The reaction is: tungsten oxide + hydrogen -->tungsten + water.

  • The tungsten oxide is reduced to tungsten and hydrogen is oxidised to water. 
  • Hydrogen has caused the tungsten oxide to be reduced. 
  • In a reaction of this type hydrogen is known as the reducing agent. It is good at reducing things because it is keen to oxidise itself to water. 
  • Carbon monoxide is another good reducing agent because it is keento get itself oxidised to carbon dioxide.

Other good reducing agents are the metals at the top of the reactivity series, as they are the keenest to lose electrons and become ions.

That is all!
