Deicing fluid is sprayed on an airplane before takeoff to prevent ice from forming on the wings and other surfaces. The fluid, which is usually a mixture of water and alcohol, lowers the freezing point of water so that it can no longer form ice crystals. Deicing fluid also contains corrosion inhibitors to protect the metal surfaces of the airplane from being damaged by the chemicals.
