← ScienceWhich risk significantly increases when de-icing roadways with excessive calcium chloride?
A)Accelerated corrosion of reinforced concrete✓
B)Formation of unstable perchlorate compounds
C)Reduced thermal conductivity of asphalt
D)Increased bioaccumulation within local aquifers
💡 Explanation
Excessive chloride concentration promotes *galvanic corrosion*, because the free chloride ions greatly accelerate electron transfer between dissimilar metals within the concrete leading to oxidation of the rebar; therefore corrosion accelerates dramatically, rather than other de-icing problems related to melting point.
