At What Temp Does Salt Melt. Commercially available ice melt materials include salt sodium chloride calcium chloride and magnesium chloride. Salt will work ie.
Melts at 98 degrees. Once the salt melts the snow ambient temperature becomes an important factor because it will freeze that nice melted snow into a nice shiny sheet of ice real quick if its just NaCl brine. In the highway deicing world the practical working temperature of salt is generally considered to be above 15 0 F or even 20 0 F.
The sidebar lists the melting point at 801 C 1474 F.
At What Temperature Does Salt Melt Ice. At a temperature of 30 degrees F one pound of salt sodium chloride will melt 46 pounds of ice. Once the salt melts the snow ambient temperature becomes an important factor because it will freeze that nice melted snow into a nice shiny sheet of ice real quick if its just NaCl brine. There are two reasons for this.
