Dry ice is the solid form of carbon dioxide (CO 2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Dry ice is colorless, odorless, and non-flammable, and can lower the pH of a solution when dissolved in water , forming carbonic acid (H 2 CO 3 ).
Dry ice is basically solidified carbon dioxide and is called so because the gas on solidifying gives an appearance similar to that of ice. Unlike ordinary ice, it does not melt into a liquid but changes directly into CO2gas, a phenomenon known as sublimation.
Solid carbon dioxide is called 'dry ice' because, unlike most solids, it doesn't melt into a liquid when it warms up. Instead, it sublimates, or turns directly into a gas, leaving no liquidy mess - thus earning the name 'dry'.
Solid carbon dioxide is called dry ice because it sublimates directly into gas without becoming liquid, leaving no wet residue. Step by step solution. 01. Understand the Composition. Solid carbon dioxide is composed purely of carbon dioxide molecules in a solid state. 02. Understand Sublimation.

Solid carbon dioxide is commonly known as dry ice. This is the solid form of carbon dioxide (CO2) gas, which we usually encounter in its gaseous state. When cooled to -78.5°C (-109.3°F), carbon dioxide becomes a solid. Unlike regular ice, made from water, dry ice does not melt into a liquid.
Dry Ice is usually made by shrinking and cooling the gaseous Carbon Dioxide to produce liquid Carbon Dioxide under high pressure. Solid Carbon Dioxide has a low temperature of -78°C for which it is also used as a substitute for refrigerators in freezing food products or medical products.

Why is CO2 a solid ice?
Dry ice is basically solid carbon dioxide that changes directly from a solid to a gaseous phase through the process of sublimation. Carbon dioxide in its gaseous state is a chemical compound that is odor-free, colorless and tasteless.
