oxidisation

Thân thiện

A piece of iron left outside slowly turns reddish-brown due to oxidisation.

Definition

Noun: 1. The process of oxidizing; the addition of oxygen to a compound with a loss of electrons: A chemical reaction where a substance combines with oxygen or loses electrons. This process is always accompanied by a corresponding reduction reaction in another substance.

Usage

The term 'oxidisation' is used to describe a fundamental chemical process. It is the standard British English spelling; the American English spelling is 'oxidization'. It is commonly used in scientific, industrial, and everyday contexts to describe reactions involving oxygen, corrosion, or electron transfer.

Examples

• The oxidisation of iron results in the formation of rust.
• In metabolism, the oxidisation of glucose provides energy for cells.
• The rapid oxidisation of the metal was a safety concern.
• Catalysts are often used to control the rate of oxidisation in industrial processes.

Advanced Usage

• Electrochemical Context: In electrochemistry, oxidisation is defined strictly as the loss of electrons by an atom, ion, or molecule, regardless of whether oxygen is involved.
  • Example: In a battery, the oxidisation reaction at the anode releases electrons.
• Biological Context: Often referred to as biological oxidation, it's a series of electron-transfer reactions crucial for respiration.
  • Example: The oxidisation of fatty acids is a key metabolic pathway.

Variants and Related Words

• Oxidization (noun): The American English spelling of 'oxidisation'.
• Oxidise (verb, British English): To undergo or cause to undergo oxidisation.
  • Example: Copper will slowly oxidise when exposed to air.
• Oxidize (verb, American English): The American English spelling of 'oxidise'.
• Oxidation (noun): The more common and internationally recognized term for the same chemical process. 'Oxidisation' and 'oxidation' are synonyms.
• Oxidising Agent (noun, British English): A substance that causes oxidisation by accepting electrons.
• Oxidizing Agent (noun, American English): The American English spelling.

Synonyms

• Oxidation
• Corrosion (specifically for metals like iron)
• Tarnishing (specifically for metals like silver)
• Combustion (rapid oxidisation with heat and light)
• Rusting (specifically the oxidisation of iron)

Antonyms

• Reduction (the chemical process of gaining electrons or losing oxygen, which always accompanies oxidisation)
• Deoxidisation / Deoxidation
