Yes, dry ice is pure.

Understanding Dry Ice Purity

Dry ice is the solid form of carbon dioxide (CO₂). The statement provided confirms this: "Dry ice is pure carbon dioxide (CO₂)." This means it's comprised almost entirely of CO₂ molecules, with negligible impurities. Its purity is a key characteristic that defines its properties and applications.

Properties of Pure Dry Ice:

  • Composition: Almost entirely carbon dioxide (CO₂).
  • Temperature: Extremely cold (-78.5°C or -109.3°F).
  • Sublimation: It transitions directly from a solid to a gas (sublimation) without becoming a liquid at standard atmospheric pressure.

Unlike many other substances, dry ice's production process typically results in a high level of purity. This makes it suitable for various applications where purity is crucial.
