because water with a solute has a lower freezing point than pure water. the freezing temp of water is 0 C but salt water is about -1.8 C it lowers with the amount of salt added to the road.

What causes road salt to pollute?
Road salt is one of the methods use to melt ice on roadways during the winter. Because of the chloride it contains, it is a water pollutant.
Is salt the only thing used to melt road ice?
No just salt
How do different concentrations of salt and sugar solutions affect the melting rate of ice?
Salt makes ice melt quicker and suger causes the ice to melt slower.
Why does salt melt ice faster than sugar or sand?
Salt. Salt dissolves in water, and causes the freezing point to fall; this causes the ice to melt. Sugar does not have this effect, and chalk doesn't dissolve in water.
What makes ice melt the fastest sugar salt pepper or sand?
SALT DOESNT MELT THE ICE IT JUST LOWERS THE FREEZING POINTWell Salt Does Make Ice Melt Faster :) I made the project and my result were correct SALT melts ice faster :)
Does salt melt ice faster than oil?
Yes, salt dissolves in water and when it dissolves, some heat is produced that causes more ice to melt and dissolve more salt. Salt lowers the freezing point of water so the water that melted from the heat of solution will not re-freeze. Salt has little effect on the ice on a road, initially. Pressure on the ice from traffic causes the ice to melt. If salt crystals have been sprinkled on the ice the effect is improved. Oil, on the other hand, does not dissolve in water to any effective extent at all. It would have no effect on lowering the freezing point of water. It could insulate the ice from being heated by warm air or if the oil is very dark in color, it could absorb heat from solar radiation and melt the ice. That effect is what causes ice to melt when soot and cinders are sprinkled on it.
Which melts faster salt water or non salty water?
Salt water freezes at a lower temperature, which is why salt is used to melt road ice. In an environment where the temperature is slowly getting warmer as to melt the ice, frozen salt water will melt quicker than ice.
Is salt the same as ice melt?
no, but ice melt is a salt
Where is salt used on ice?
All over the ice is when they need to melt the ice. So they would get alot of salt and pour it all over the ground or road.
Why do you use rock salt?
To melt the ice and snow and to give your tires grip on the road.
Why have states in new England stopped using salt to melt ice?
Road damage and pollution.
What causes salt to melt water?
Salt lowers the freezing temperature of water/ice therefore the water/ice needs to be colder then usual to freeze.
