oxidiser

Thân thiện

A scientist carefully adds an oxidiser to a chemical solution.

Definition

Noun: A chemical agent that causes oxidation by accepting electrons from another substance during a redox reaction. It is the substance that is reduced (gains electrons) in the process.

Usage

An oxidiser is a core concept in chemistry, describing a substance that facilitates or causes oxidation. It is a key component in combustion, respiration, and many industrial processes. * In a fire, the oxidiser is typically the oxygen in the air. * Rocket fuels often require a powerful liquid oxidiser to burn in the vacuum of space. * Chlorine can act as an oxidiser in water treatment to disinfect it.

Examples

• Noun:
  • Oxygen is the most common oxidiser in atmospheric combustion.
  • The laboratory stored the strong oxidiser in a special safety cabinet.
  • In the chemical reaction, the nitrate ion served as the oxidiser.

Advanced Usage

• "To act as an oxidiser": To function in the role of an electron-accepting agent.
  • In this battery chemistry, the cathode material must act as an oxidiser.
• "Strong/Powerful oxidiser": An oxidiser with a high tendency to gain electrons, often reactive or hazardous.
  • Potassium permanganate is a strong oxidiser used as a disinfectant.

• Oxidizer (noun): An alternative spelling, primarily used in American English.
• Oxidizing agent (noun): A synonymous term for oxidiser.
• Oxidant (noun): Another synonymous term, commonly used in environmental and atmospheric chemistry.
• Oxidise/Oxidize (verb): To undergo or cause a reaction with an oxidiser. (e.g., )
