Definition

1. 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.

Variants and Related Words

• Distill (verb): To purify a liquid by heating it until it vaporizes, then cooling the vapor to collect the condensed liquid.
  • They distill seawater to make it drinkable.

Synonyms
