Ethylene glycol is a compound used in automotive antifreeze. It is odorless, colorless, and toxic if ingested. Adding ethylene g

lycol to water affects the freezing and boiling point. Two students predict the freezing point for 100% ethylene glycol. Andre predicts the freezing point will be less than that of 100% water. Jennifer predicts the freezing point will be about the same as 90% ethylene glycol in water. Which inference seems MOST plausible?

Answer: Andre. If it is used as an antifreeze, one would infer that it's freezing point is less than water.

Explanation:

The freezing point of ethylene glycol alone (100%) is -12.9oC. That is somewhat less than the freezing point of water but nowhere near the freezing point of water containing 70% ethylene glycol.
