Because it melts the ice. Salt melts ice within a certain temperature range. If the weather is sufficiently cold, the ice won't melt even if salt is used, however it's usually not that cold. Salty water has a lower freezing temperature than pure water.
yes
The salt used on icy roads in winter is quarried from underground salt deposits (salt mines), which are the remains of ancient salty seas. Salt is not extracted from fresh water.
To increase friction on an icy roadway, you can apply materials such as sand, salt, or gravel to the surface. These materials help to provide better traction for vehicles driving on the icy road. Additionally, reducing speed and avoiding sudden changes in direction can also help maintain control on icy roads.
for sure
yes.
salt is what the states use
Adding salt the freezing point of water is lowered.
It is recommended to use salt or sand to increase traction on icy roads. Sand provides grit and improves grip, while salt helps to melt the ice. It is important to drive cautiously and slowly on icy roads to prevent accidents.
salt doesn't change the temperature of water, it changes the freezing point. salt lowers the freezing point of water so that it will become ice at a lower temperature, therefor melt at a lower temperature which is why salt is put on the roads when it is icy

Yes, applying salt before icy conditions can help prevent ice from forming on sidewalks. Salt lowers the freezing point of water, making it less likely for ice to develop when temperatures drop. However, its effectiveness is best when applied before precipitation begins. Keep in mind that continuous application may be necessary during prolonged cold spells or heavy snowfall.
