Which consequence results when high humidity contacts magnesium chloride pavement deicer?

A)Increased ionic conductivity accelerates corrosion
B)Reduced freezing point prevents road ice
C)Endothermic reaction lowers pavement temperature
D)Covalent network resists mechanical abrasion

💡 Explanation

Magnesium chloride absorbs water through hygroscopy; therefore, increased free ions in solution raise the medium's conductivity, thus accelerating galvanic corrosion via electrochemical reactions, rather than simply lowering freexing, because other mechanisms can provide freezing point depression.
