When you mix two liquids 50/50, and one has a freezing point of 20 Celcius and the other has a freezing point of 0 Celcius, does the new liquid have a freezing point of 10 Celcius?

It’s way weirder than that.
For example: standard car antifreeze is made of ethylene glycol. Pure ethylene glycol freezes at -13c.
A 50-50 mix of water and ethylene glycol freezes at… -37c!
Mix the two and the freezing point is *MUCH lower than the freezing point of either of the two components of the mixture!*
So freezing points aren’t all that predictable. There’s a curve based on the concentration but that curve won’t necessarily stay between the two starting points.
