← ScienceWhich consequence results when high humidity contacts road de-icing salt?
A)Increased electrolyte concentration corrosion✓
B)Decreased surface friction coefficient
C)Elevated freezing point depression
D)Reduced particulate matter suspension
💡 Explanation
Salt (NaCl) dissolution leads to ionic species which promotes galvanic corrosion; this process corrodes metals because the dissociation provides readily available charge carriers. Higher humidity accelerates this, therefore, corrosion increases due to enhanced ion mobility, rather than friction decreasing under these conditions.
