Why is calcium chloride (rock salt, CaCl2) more effective than sodium chloride (table salt, NaCl) at de-icing roads in the winter? A. Calcium chloride only breaks into 2 ions, while sodium chloride does not break up and remains 1 ion. B. Calcium is a larger molecule than sodium, so it has a greater effect. C. The additional chlorine atom forms a stronger bond between the atoms in calcium chloride than in sodium chloride, so calcium chloride remains one molecule while sodium chloride breaks apart. D. Calcium chloride breaks into 3 ions, while sodium chloride only breaks into 2 ions.
