yes
I use rock salt to melt ice and use my brocast spreader to scatter it on my driveway. I have also used the spreader to apply other ice melting products as well with no problem.
Yeah, its good for a lot of things.
Adding a salt the freezing point of water decrease.
No. Rock salt is used to make ice cream and melt ice on roads. Regular salt is not good for blood pressure because it will raise it.
It's due to the material in the salt that allows the ice's mass to lower. The temperature doesn't effect the process in a good way. Actually, it helps the ice melt more with the salt material.
ice, because that it what they are designed for.
Saltwater freezes too, just at a couple degrees lower than fresh water.
Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius). When you add salt, that temperature drops: 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 saltdissolves into the liquid water in the ice and lowers its freezing point.

salt. salt melts ice.
Rock salt is cheapest, table salt works just as good. These will cool the salt and ice to about 10F. There are other salts that will get the salt and ice mixture colder, but they are generally more expensive and harder to get in quantity. If you want to experiment (and will be very very careful never to accidentally contaminate the ice cream mixture) you could test some of the "Ice Melter" products used on sidewalks in winter, some of these should cool the salt and ice somewhat below 0F. But these could be toxic!
