How solid carbon dioxide is formed?
Dry ice is the solid form of carbon dioxide (CO2), a molecule consisting of a singlecarbon atom bonded to two oxygen atoms. Dry ice is colorless, non-flammable, with a sour zesty odor, and can lower the pH of a solution when dissolved in water, forming carbonic acid (H2CO3).

How solid carbon dioxide is formed?
Solid carbon dioxide is called dry ice. It is called because when it is exposed to air , the pressure acting on it falls to about 1 atmosphere .As a result , it sublimes ,i.e., directly gets converted into gaseous carbon dioxide without passing through the intervening liquid state . Consequently , unlike ordinary ice , it does wet the surface on which it is kept . That is why it is called dry ice . It is prepared by cooling carbon dioxide under pressure.
