Just Guessing,
I'll say that the Popsicle's will freeze first, then the road salt and
last, the anti-freeze in the car.
No reason, just being intuitive.
We never did say what the quality of the DI water was, so I agree with KB
that the DI water has something to do with it. I sense a connection to the
threads concerning DI water.
I don't think the final answer will give me a bloody nose as suggested by
the originator.

Shawn,
Need some clarification.
The term "Road Salt" means sodium chloride in my neck of the woods,
calcium chloride too expensive as a road salt. Which one?
Just 20 ml of water?
Please advise.

[TN] Friday question
This one's real fun. It's sure to make blood shoot out your nose.
Which of these 3 solutions will freeze first, second, and third and WHY
will
they freeze in that order????
1) 10 grams of Calcium Chloride (road salt) dissolved in 20 mL of DI
water.
2) 10 grams of Sucrose (table sugar) dissolved in 20 mL of DI Water.
3) 10 grams of Ethylene Glycol (antifreeze) dissolved in 20 mL of DI
water.

Re: [TN] Friday question
You can tell it's Friday, I threw Sodium Chloride into the mix. I really
need the weekend.
I amend my list to:
Antifreeze first
Sugar second
Salt last

OK, if no one else will dip their toes in the water, I'll give it a shot.
Ethylene Glycol will freeze first
Sodium Chloride second
Calcium Chloride third
Having said that I think it's a trick question because of the DI water.
I'm certainly not a chemist and only guessing.
Happy Friday,
KennyB
