oxidiser
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.
