Sodium chloride (salt) lowers the melting point of ice - so it turns back to water at a lower temperature that it would normally.
Ice melts when it gets warmer. The ice is receiving energy in the form of sunlight no matter how reflective it is. When the ice is reflective, the energy turns around and leaves as reflected sunlight. Less reflective ice has more of the energy stay in the ice as heat, warming it up and melting it faster.
Basal flow :) :) :)
melting ice a physical change
NaCl, sodium chloride, aka salt the mineral used on slippery winter surfers is called (HALITE)
During melting the chemical composition of NaCl is not changed.
it's manly consists of salt (NaCl) and helps lower the melting point of ice. It breaks the hydrogen bonds that holds the water molecules in place, therefore melting the ice, but that is quite detailed chemistry.
NaCl has the highest melting point (between NaCl and H2O)
Dissolving a salt (NaCl, CaCl2) in water the heat of dissolution is released and the melting point of ice is then decreased.
Adding salt to ice decreases its melting point. Adding salt to the top of ice helps melt the ice faster.
Calcium chloride is better (the solubility heat is greater) but is more expensive.
The ion chlorine from NaCl or CaCl2 is corrosive for metals (all type of vehicles) or roads.

Melting point of NaCl: 801 0C Boiling point of NaCl: 1 413 0C.
Melting ice turns the ice into water.
We can use sodium, calcium and potassium chlorides; NaCl is the cheapest, calcium chloride is the most efficient but is more expensive.
To decrease melting point of NaCl
Because NaCl is stable to thermal degradation and is an ionic compound.
