Calcium chloride is a liquid brine in its natural state and is converted into a dry material by removing the water. It quickly absorbs moisture from the atmosphere, while rock salt, potassium chloride and urea must come in direct contact with moisture, which is not available at low temperatures.
Calcium carbide is converted into acetylene in a controlled reaction with water using an apparatus called a generator. Acetylene, which has the chemical formula C2H2, is an extremely useful hydrocarbon due to the energy that is locked up in the triple-bond between the carbon atoms.
