WebAug 8, 2016 · Pure ethylene glycol has a freezing point of #-12.9^@ "C"#, and water's freezing point is #0^@ "C"#. So, the solution's freezing point should actually be below #\mathbf(0^@ "C")# (what occurs is freezing point depression due to colligative properties of adding solutes into a solvent, so the freezing point should drop).
