Are ice cubes in China are safe to use?

Can you really dissolve ice with table salt?

  • I understand that, from a scientific perspective, there is more than one kind of salt. The salt that we typically use as a seasoning on our food is called sodium chloride, aka table salt. My car is currently stuck in ice in a restaurant parking lot. I live within walking distance of this restaurant (and, as a direct result, I'm a regular customer there), but the walk (as opposed to the drive) is still F'ing brutal! I can't go forward, because that giant stone slab is in the way, and I can't back up because there's too much ice. I don't wanna pay out the *** for a towing service. My neighbor just told me that, in the morning, I can just sprinkle some salt onto the ice, and it will dissolve the ice enough for me to get out of there, but I didn't question him as to whether he actually did it himself, or just heard about it happening, before. See, the city will actually use some kind of salt to dissolve the ice on the streets, but I don't know if the city actually uses sodium chloride. Is this even theoretically possible? Can you really dissolve ice with sodium chloride? I don't have any table salt with me, so I can't just make some ice cubes and find out in my own qsuedo-lab (but, then again, that would probably be a totally different environment, right there), so I have no choice but to ask you guys.

  • Answer:

    Yes table salt will dissolve ice. But a piece of ice that large you would need a hell of a lot of salt, so unless you have a lot of it, than it probaly won't work

You can technically use any small particles. It's just that salt is often found in abundance and when everything dries, it doesn't leave as much of a mess like gravel or sand. It works by mixing with the snow... ice.. whatever, and it lowers the freezing point. A 10-percent salt solution freezes at 20 F (-6 C), and a 20-percent solution freezes at 2 F (-16 C). On a roadway, this means that if you sprinkle salt on the ice, you can melt it. The salt dissolves into the liquid water in the ice and lowers its freezing point.

Yep. As the concentration of a solute increases, the freezing point of the solvent as a whole will decrease. Or, it will need to be colder for the ice to stay frozen if there's salt in there.

Yes, it's true. You CAN dissolve ice with table salt, i've done it many, many times!
