Salt works as an ice melt because it lowers the freezing point of water, from 32 degrees F for plain water to about -6 degrees F for salt water. In our test, we used kosher salt, which is coarse and thus provides a bit of grittiness for traction during the melting process.
Similarly one may ask, will coarse sea salt melt ice?
Salt Lowers the Freezing Point By using salt, that freezing point can be lowered which forces the ice to melt and prevents the water from freezing or re-freezing. It must be noted, however, that salt alone can't melt ice. It must first be combined with water to start the melting process.
Correspondingly, can cooking salt melt ice?
Rock salt is a great way to melt ice, but it's not the only way. Instead of rock salt, you can sprinkle a thin layer of table salt over icy areas. Heat is generated because of the chemical reaction that takes place between the salt and water, which lowers the freezing point of the water in the snow.
A 10-percent salt solution freezes at 20 degrees Fahrenheit (-6 Celsius), and a 20-percent solution freezes at 2 degrees Fahrenheit (-16 Celsius). The key is, there has to be at least a tiny bit of water on the road for freezing point depression to work.
