How cold does salt work?
At a temperature of 30 degrees (F), one pound of salt (sodium chloride) will melt 46 pounds of ice. But, as the temperature drops, salt’s effectiveness slows to the point that when you get down near 10 degrees (F) and below, salt is barely working.Click to see full answer.

In this regard, how cold does it have to be for salt to stop working? 15 degrees Secondly, does salt melt ice at 20 degrees? A 10-percent salt solution freezes at 20 degrees Fahrenheit (-6 Celsius), and a 20-percent solution freezes at 2 degrees Fahrenheit (-16 Celsius). The key is, there has to be at least a tiny bit of water on the road for freezing point depression to work. Similarly, it is asked, does salt work in freezing weather? Salt lowers the freezing temperature of water, which prevents ice or frost forming on the carriageway as it would otherwise, once the temperature of the road or the air falls to zero degrees centigrade. Generally, on the roads, salt loses its effectiveness once the temperature falls below -10 degrees centigrade.Does salt make water colder?Because salt lowers the melting point of water, if you add salt to ice, the ice will melt. Salty ice water can get much colder than regular water, though. While salty 0°F ice will still melt, its temperature won’t increase to 32°F like it would in regular water. Instead, the salt will turn it into 0°F water.
