That's why you see the salt trucks out before the snowfall. They spread salt or more often "ice melt" in the dangerous areas like stop signs and turns before the event.
The same thing holds true for you at home. Spreading ice melt or placing ice melt filled snow socks, before a snow event, allows the first precipitation to mix with the ice melt crystals and form a flowing liquid deicer. If the liquid is allowed to drain or run-off it will keep a specific area clear of ice dams until the next event.
The minimum practical application range for salt is a pavement temperature of 15-20 degrees F and above. While salt will melt snow and ice down to a pavement temperature of -6 degrees F, it can melt over five times as much ice at 30 degrees F as at 20 degrees F. Thus the effectiveness of salt is sensitive to small differences in pavement temperature.
The reason salt causes ice to melt is because salt water freezes at a lower temperature than normal water. But when it gets so cold that even salt water will freeze, salt won't help melt your ice.
It gets very difficult below about 5 F. ( That's assuming salt means NaCl. CaCl2 will work down to about -10F)
Because the heat of solubility in water of the salt (sodium chloride, NaCl) is not sufficient to melt an ice at -15 0C.
-6 degrees Fahrenheit
When you mix salt with ice, the ice melts. In some situations, however, the ice can become extremely cold
Salt lowers the temperature at which water freezes which would cause the ice to melt.
Baking soda is a type of salt so it will melt ice like salt. It will lower the freezing point of water and the ice will melt
Salt water will melt an ice cube faster.
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.
Salt doesnt melt, it is absorbed, and as for melting on cold mornings.... name something that does melt on a cold morning.----Salt will cause water ice to soften and melt unless the temperature is very cold (much colder than you're ever likely to see this side of the arctic circle). the salt itself doesn't melt; it converts the ice around it to water and dissolves in that water, allowing it to spread out and melt more ice.
yes it can. The salt eats away at it. So the ice is disintegrating slowly even though the salt is cold.
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 :)

no, but ice melt is a salt
Salt lowers the temperature at which water freezes which would cause the ice to melt.
Yes, in fact it doesnt melt. The salt goes through the ice, then make little holes in the ice.
Yes, it will keep the soda cold because the salt help the ice not to melt. Don't believe me check it yourself. Get an ice cube put a little salt on it and it doest melt. Or get an ice cube put some salt on it and then get a string put on top and IT WILL STICK!!!!!!!
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.
because salt lowers both the melting and boiling point of water. if it is raised, then it will melt because it is no longer cold enough to freeze the water Salt doesnt melt ice; it lowers the freezing point of already molten water preventing it to refreeze and presence of water with lower F.P. means this salt water can lose more heat to ice before freezing thereby melting more ice which turns salty as soon as it melts and the process continues.
Yes, the salt on popcorn is common table salt, which can be used to melt ice.
salt. salt melts ice.
