Water question

[onfire]

I bought some jugs of water the other day One from Ice Mountain. The other from a local grocery store chain. (Same store) Had them out in the garage, The question is why did the local one freeze solid and the spring water one didn't? They were inch's apart on the same table.

Hope the ice Mt. one is Vodka

Some of bottled water has calcium chloride in it. Maybe just enough to keep from freezing?

I certainly don't know the answer to this question.... but it is a good one.

when you find out, let us know.

I think Dieselram hit it with the salt content. We use to add it to mortar cement when I was doing bricklaying so we could work in freezing weather. Frank...

So we add salt to our drinking water?? Bad... Good Did I hear this right?

(NOT MINE.... I'm lucky. I get natural soft water right out of the ground and a lot of it). I was so fortunate.

ice mountain is pure spring water?

 

[golden sluice]

If it is distilled water or water that is low in minerals, it will not freeze easily.

I sure if you jostle the bottle it would have started the of the one that didnt freeze it, it would have crystalized to ice.

Here is a thought, the ice mountain jugs, look on jug, was it bottled in Pennsylvania ? Reason I ask is we buy ice mountain in both small bottles which are bottled from springs here in Michigan, but the gallon or larger sized ones sold here are bottled in pa. The small ones freeze, but the big ones don't.
I had to shop around to find small ones from pa and what do you know they barely freeze either.
So yeah you have me very curious on that.

I have an old fashion Amish spring house for my water supply. It taste great. I had it tested by U of MD. They sent me a list of the contents and classified it as good drinking water. I called them up and asked them what all those contents were. They said it was an artesian spring and those were the minerals in it, all good. Frank...

My guess is the spring water has more dissolved oxygen. A plumber will tell you that hot water pipes freeze before cold water pipes but often don't know why. When water is heated the dissolved oxygen (the stuff fishes live on) is released. The dissolved oxygen acts as a slight freeze inhibitor. Sort of an insulation.

Why would they boil spring water? The ones that didn't freeze were bottled in Michigan. I called ice Mt. and the supervisor thought it was something called super cooling but I tried that by shaking the other one, So the mystery is

I still believe the calcium chloride is the reason. Is it listed as an ingredient on the label?

When I was in college we learned that it had more to do with covalent bonding with other h2o molecules? They relax when heated and the water is less dense.

And I agree with Diesel. It probably has to do with salt content.

I don't care what one froze. Not saying anyone boiled the water. It's just a matter of dissolved oxygen. You don't have to cook water to release oxygen. You can let it sit just the way a glass of water will go flat after being in the air for awhile. The flat taste is lack of dissolved oxygen.
Supercooling is another thing. Water droplets in the upper atmosphere can exist in clean air down to temperatures as low as -40degC. The freeze point of water changes with pressure same as the boiling point.
Just saying what ever jug froze had less dissolved oxygen that the other.

Salt lowers the boiling point too but you would notice the taste. You'd need to test percentages in distilled water along with different minerals. The 32 degF is with distilled water at sea level.

If I were bottling water and selling it to the masses you can bet I would filter it, boil it, chlorinate it, soften it (by exchanging cl for na) and I might even ozonate it and then Ultraviolet light it! Then have a continuous auto sampling for chemical traces. But it wouldn't come out of the ground and get sent straight to the public,, nooooo.

Sure is litigious out here.
And THAT is why we have beer.

The water you describe would have NO customers. In my home because I'm on a well and do at times have sulfur dioxide I run my water through a green sand filter then to a ion exchange softener then to an activated carbon filter. It's OK but it's not as good as many natural spring waters are. What makes good water is when no one messes with it. Good spring water has a good balance of minerals and enough dissolved oxygen to give it the sparkle people want. It's all because it's natural that we like it.
Your idea of water is what many municipalities send to your tap. BTW you forgot to fluoridate it.
