It has to do with the total number of particles in solution. In this
case, the smaller the number, the faster it freezes..and vice versa. I
begin with the same weight of material, 10 grams, but I have to take
each formula weight into account as well.
Popsicles also have other ingredients, such as flavorings, etc.
Anti-freeze has methanol along with the glycol to help lower it's
freezing point.

I disagree.
Why do Popsicle's stay frozen in my freezer while the anti freeze in my
car is protects my car to 20 below F.
Certainly my freezer doesn't go to 30 below F.
Now I know why I'll get a bloody nose.

[TN] Answer to Friday's question
Alright,
First of all, that much sucrose or calcium chloride will not completely
dissolve in that little of DI water. So, the original question was a
tad bit on the devious side.
However, if you did use enough DI water to completely dissolve each of
those materials, they will begin to freeze in this order: First to
begin freezing is the ethylene glycol (antifreeze), second will be the
calcium chloride (Indiana's road salt), and last is the sucrose (sugar).
Happy Friday!

You are what we call over here, a real stinker! Its Friday and I am not
less than 5 hours ahead of all you guys and now I will have to spend the
entire week-end wondering about the true answer.
My shot will be Calcium Chloride time because of the De-ionised water,
then sucrose unless the water is hot, then the diluted anti-freeze. I
haven't a clue as to why, just gut feeling.
