Thân thiện

This metal will oxidate if left outside in the rain.

Definition

1. Verb (transitive):

   • To cause a substance to combine with oxygen; to add oxygen to a chemical compound or element.
   • To convert a substance into an oxide through a chemical reaction.

2. Verb (intransitive):

   • To undergo a chemical reaction with oxygen; to become converted into an oxide.
   • To become rusty or tarnished, especially for metals.

Usage and Examples

• Transitive Verb (to cause oxidation):

  • The process will oxidate the metal, forming a protective layer.
  • Scientists can oxidate the compound in a controlled environment.

• Intransitive Verb (to undergo oxidation):

  • Iron will oxidate when exposed to moist air, forming rust.
  • Many fruits, like apples, oxidate quickly after being cut.

Advanced Usage and Notes

• Technical vs. Common Usage: In chemistry, "oxidate" is a precise term for the reaction with oxygen. In everyday language, "rust" or "tarnish" are more common for describing the visible effects on metals.
• "Oxidate" vs. "Oxidize": "Oxidize" is the far more common and preferred term in modern English for all meanings of "oxidate." "Oxidate" is considered a less frequent variant.

Variants and Related Words

• Oxide (n): A chemical compound of oxygen with another element.
  • Iron oxide is commonly known as rust.
• Oxidizable (adj): Capable of being oxidized.
  • This is a highly oxidizable material.

Synonyms

• Oxidize (verb): The primary and most common synonym.
• Rust (verb, intransitive): Specifically for the oxidation of iron and its alloys.
• Corrode (verb): To wear away, typically by chemical action like oxidation.
• Tarnish (verb): To lose luster, especially for metals like silver due to oxidation.

Antonyms

• Reduce (verb, chemistry): To cause to undergo reduction; to remove oxygen from or add hydrogen to a compound.
• Deoxidize (verb): To remove oxygen from.

Related Chemical Concepts

• Redox Reaction: A chemical reaction involving both oxidation (loss of electrons) and reduction (gain of electrons). Oxidation is not limited to reactions with oxygen but includes any loss of electrons.
• Combustion: A high-temperature oxidation reaction, usually with rapid release of heat and light (e.g., burning).
