Salt does not cause ice to melt. Instead it mixes with water to make salt-water which has a lower freezing point---meaning it will not freeze until the temperature gets below 32 Degrees F. When Salt is put on roads and sidewalks, it does give you traction. Then when the sun or the cars cause the ice to melt, the ice PREVENTS it from re-freezing. This was discovered long time ago. But 100 years ago, salt was a valuable commodity and they would not have thrown it on the ground. Also, a hundred years ago, there were no paved highways or concrete sidewalks so no one needed to use salt on dirt roads.

How fast does 2 tablespoons of salt melt 5 pints of melted ice?
Instantly, the ice is already melted. If the ice weren't melted, it would depend on what salt was used and the temperature of the salt and the ice. Certain salts, like magnesium chloride, melt ice much faster and at a lower temperature than table salt. If the ice is really cold it won't melt, regardless of what salt is used.
What do that salt do to the ice?
The ice is melted because the heat of solubilization of NaCl is released.
What happens when you heat ice and sodium chloride?
Ice is melted over 0 0C and salt is melted over 801 0C.
What would the Effect of adding salt to ice?
No, because the data does not show how quickly the ice would have melted without the salt.
What is ice melt rock salt?
The sodium chloride heat of solution increase the temperature and the ice is melted.
Why does the string stick to the ice when you put salt on it?
The salt temporarily melts the ice. The melted water flows over the string. The water refreezes on top of the string.
Why when salt is poured on ice the ice melts?
Salt lowers the freezing temperature of water to some extent, so ice at 0°C can be melted to some porportion of ice at a lower temperature and brine.
If salt water was froszen and melted back again will it be salt water?
Salt is expelled as the ocean water freezes to form sea ice
What happens when sand is scattered on icy roads?
The sand helps melt the ice. I did an experiment. I put three ice cubes in 1 bowl without ice. The other bowl had salt and ice. The one with salt melted the quickest.
Why does the salt level not change in the oceans?
The salt level does not change in the ocean because over a billion years ago the Ice Age Period was here on earth and all oceans where solid Ice and when Global Warming set in motion all the Ice melted and the bottom of the ocean floor is salt so when it melted the salt came above the water and the glaciers mixed with that and glaciers are mostly made out of Ice (mostly 321 feet tall) so it never changes.
Does salt coduct electricity when melted?
Salt does conduct electricity when melted.
Can you melt ice with laundry detergent?
AnswerSalt melts ice. Laundry detergent is like salt it lowers the melting temp and also creates traction
