No one really invented it. For many years, salt has been known to lower the freezing point of water. This happens when the salt's ions dissociate in water. The act of lowering a freezing point (or raising a boiling point) is called water's colligative property. Generally speaking, the more ions in solution, the lower temperature at which water will freeze. The salt used on roads is usually calcium chloride (CaCl2).
The inventor of using salt to de-ice roads is not definitively known, but it is believed to have originated in the United States in the early 20th century. Initially, salt was used in small amounts, and its effectiveness in melting ice and snow led to widespread adoption for winter road maintenance.
Putting salt on ice or snow decreases the melting point of water, a process known as freezing point depression. When salt is added, it disrupts the formation of ice crystals, causing the ice to melt at lower temperatures. This is why salt is commonly used to de-ice roads and walkways in winter.
salt melts all ice thus clearing the roads for transport
because the sodium chloride is salt and we use it in the roads because the salt melt the ice
Sprinkling salt on icy roads doesn't warm up the ice. What it does is depress the freezing point of water to the point where the ice is too warm to be solid, even though it is just as cold as before.

Salt melts ice.
salt melts all ice thus clearing the roads for transport
it slowly burns it with the chemicals in the salt
Road salt pollution is caused by the use of salt (sodium chloride) for de-icing roads in winter. When snow and ice melt, the salt used on roads washes into nearby water bodies, leading to elevated levels of chloride in the water which can harm aquatic life and vegetation.
Salt is good 4 roads cause it lowers the freezin point of ice and it makes the roads less slippery x
Utah uses salt, sand, and liquid ice-melt on the roads during winter.
because the sodium chloride is salt and we use it in the roads because the salt melt the ice
for melting ice on roads and sidewalks.
Indiana primarily uses rock salt (sodium chloride) to melt ice on roads. This salt is effective in lowering the freezing point of water, causing ice to melt and provide better traction for vehicles. Sometimes, a mixture of salt and sand is used for additional traction on roads in Indiana.
because it will melt the ice on the sidewalks.
