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).

Who was the inventor of putting salt on icy roads?
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.
If you put salt on ice of snow decrease the melting point or increase it?
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.
Why salt is sprinkled on roads when it snows?
salt melts all ice thus clearing the roads for transport
Why sodium chloride used on roads in winter?
because the sodium chloride is salt and we use it in the roads because the salt melt the ice
Why does salt sprinkle on ice roads cause ice to melt?
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.

Why you sprinkle the salt on the frozen roads?
Salt melts ice.

Why salt is sprinkled on roads when it snows?

How does salt melt ice on roads?
it slowly burns it with the chemicals in the salt
What causes road salt pollution?
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.
Why is salt good for roads?
Salt is good 4 roads cause it lowers the freezin point of ice and it makes the roads less slippery x
Does Utah salt their roads in winter?
Utah uses salt, sand, and liquid ice-melt on the roads during winter.
Why sodium chloride used on roads in winter?
because the sodium chloride is salt and we use it in the roads because the salt melt the ice
What is utahs salt used for?
for melting ice on roads and sidewalks.
What salt does Indiana use to melt the ice on roads?
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.
Why do people use salt on icy roads?
because it will melt the ice on the sidewalks.
