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). [1]
Dry ice is solid carbon dioxide that turns directly into gas at standard atmospheric pressure. It is used for refrigeration because it stays very cold.
Dry ice is the name given to carbon dioxide when it is in a solid state. Carbon dioxide is found in the earth's atmosphere; it is a gas that humans exhale and plants use for photosynthesis. This chemical compound is colorless, odorless, tasteless, and about 1.5 times as dense as air.
