Determine what the experimental variable is. how does salt change the freezing temperature of water?

Salt melts ice essentially because adding salt lowers the freezing point of the water. ... Ice typically is coated with a thin film of liquid water, which is all it takes. Pure water freezes at 32°F (0°C). Water with salt (or any other substance in it) will freeze at some lower temperature.

Hope This Helps :)

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
