Why are salt solutions not used to treat the roads during snow events when the temperature is below -15 degrees Celsius? *
A. Salts are nonelectrolytes and do not demonstrate the Van't Hoff Factor.
Therefore the freezing point cannot be depressed lower than -15 C.
B. The solubility of a salt will decrease with decreasing temperature making it even more difficult to concentrate a solution. The maximum quantity that can saturate a solution and attain the maximum molality that aligns with solubility values at that low of a temperature cannot provide the multiplier high enough to depress the freezing point to temperatures below -15 C.
C. Salt has a maximum molality of 0.6m.
D. Salts can melt ice but cannot prevent freezing.
