I have seen this after laying "salt" on the sidewalks in front of my home and on our driveway. The little salt pieces are still there after the snow starts to melt away. I haven't seen ice on it yet.

The lowest temperature at which sodium chloride will melt ice (the eutectic point) is -21.12° C (-6.02° F), at a concentration of 23.3% NaCl. Salt works best at temperatures near 0° C (32° F) because melting occurs quickly with a relatively small amount of salt. As the temperature falls, it takes more salt and more time to melt ice because a higher concentration of brine is required. Wink
