Expert Answer:

A de–icing agent is a substance that prevents the formation of ice.

Example 1:

NaCl is a de–icing agent as it lowers the freezing point of water so that it doesnot freeze to form ice under a particular temperature range. Therefore, it is used to clear snow from roads.

Example 2:

De-icing an airplane is extremely important since ice can create drag on an airplane and make it difficult to fly. The FAA has a couple of ways of de-icing a plane. The first is spraying the plane down with a glycol based chemical that removes ice and leaves a film that prevents new ice from forming. Some airports have an infra-red 'airplane' wash that removes ice.
