Definition
- Noun:
- Water purified by distillation: Distilled water is water that has been boiled into steam and then condensed back into liquid in a separate container. This process removes impurities, minerals, and contaminants.
Usage
- Distilled water is used in contexts where pure water is required, free from dissolved salts and other substances.
- It is commonly used in laboratories, automotive cooling systems, steam irons, and certain medical or pharmaceutical applications.
Examples
- Noun:
- The experiment requires distilled water to ensure accurate results.
- You should use distilled water in your humidifier to prevent mineral buildup.
- The battery is filled with distilled water.
Advanced Usage
- "Double-distilled water": Water that has undergone the distillation process twice for an even higher level of purity, often used in sensitive analytical chemistry.
- "Deionized water" vs. "Distilled water": While both are purified, deionized water has had its mineral ions removed through a chemical process, whereas distilled water is purified through phase change (evaporation and condensation). They are often used interchangeably in casual contexts but differ in specific technical applications.
