salt is a pure substance because it is created using natural products that were drawn from our environment. in the refining process, there are no chemicals or other new substaâ¦nces added to the original products that would make it a mixture.
The science behind how salt works lies in something known as the freezing point. Salt has a lower freezing point than water, which is why salt water does not freeze as quickly as pure water. This lower freezing point is what enables salt to melt ice and snow. When you spread salt on ice, it acts almost like a molecular sponge. It draws some of the frozen water molecules to it and, because of its lower freezing point, breaks the molecular bonds between them. These broken molecular bonds cause the ice to melt, creating a brine that encourages further melting.
