Subject: Calcium Chloride Best Purchase for Deicing
Enclosures: (1) Data Record (2) Data Treatment (3) Environment Impact Research
After hours of vigorous examination, we have come to the conclusion that calcium chloride (CaCl2) would be the best deicer to use on a naval base over sodium chloride (NaCl) and ethylene glycol (C2H6O2). In order to melt ice, deicers lower the freezing point so that the ice melts at lower temperatures. CaCl2 has a freezing point depression of 5°C, whereas NaCl has only a 3°C depression, and ethylene glycol, 1.85°C. The more the freezing point can be lowered, the faster the ice will melt, and more effectively. The reason to look at this is due to the fact …show more content…
There is no reason to destroy our environment or humanity if we can find a way around it. NaCl may be soluble in water, and may not chemically attack concrete, but the sodium ion in NaCl is toxic to vegetation, as well as the water supply. When NaCl decomposes at/around 20°C, the toxic sodium ion threatens our environment. Sodium can vigorously react with water, which can lead to death of our animals in the environment. After ice storms, NaCl can be found on many cars and sides of the road due to it's trouble with dissolving easily. On the other hand, ethylene glycol is very toxic. In large amounts, just inhaling the solution can burn your lungs. Ethylene glycol leaves a greasy residue behind, and due to it's neon color, it can be seen as attractive to animals and children. Also, ethylene glycol is an odorless, sweet tasting solution, therefore it can be hard to tell if it is harmful or not without knowing it is ethylene glycol. Just the fact that it is extremely toxic to aquatic life and humans around puts ethylene glycol out of the picture. Now, CaCl2 may be corrosive to concrete, but it can evaporate easier than NaCl. Since CaCl2 has a minimum effective temperature of -30°C, not as much solution would be used as NaCl would be used. CaCl2 is also usually added to an area in a liquid form, whereas NaCl would be solid. Through tests, calcium in general has been found to be less toxic than
