Salt Lowers the Freezing Point. In a nutshell, salt is a great ice melter because it causes “freezing point depression.” This means that salt helps in lowering the freezing point and, consequently, the melting point of water (the main component of snow and ice).
In this manner, can I use table salt to melt snow?
It is just like ordinary salt in chemical composition but has larger and coarser grains. Although not frequently used as rock salt, ordinary table salt too can be used to melt ice. In fact, it is far more effective than rock salt at melting ice.
What type of salt is used to melt snow?
Unlike table salt, road salt is not for licking! While both begin as sodium chloride, the coarse mix used on roads and highways contains high levels of chemicals such as sodium ferrocyanide and ferric ferrocyanide that prevent caking during storage.
Which salt is best for melting snow?
Magnesium chloride is the newest deicing salt. It continues to melt snow and ice until the temperature reaches -13 F. The salt releases 40% less chloride into the environment that either rock salt or calcium chloride. It is far less damaging to concrete and plants. It is the best choice.
