why do we put salt on sidewalks when it snows?
The biggest reason for pouring salt on icy roads is that salt lowers the freezing point of water. Water normally freezes at 32 degrees Fahrenheit, but when you add salt, that threshold drops to 20 degrees (or even 2 degrees) Fahrenheit

also if your still here could you help the guy under me with his question about math?
We put salt on sidewalks when it snows to melt the snow and prevent it from accumulating. Salt lowers the freezing point of water, causing the ice to melt and turn into water. This helps to create traction on the surface and make it safer for pedestrians to walk on the sidewalk. Additionally, salt helps to prevent the formation of black ice, which is a thin invisible layer of ice that can be especially dangerous because it is difficult to detect.
To effectively use salt on sidewalks, you can follow these steps:
1. Prepare by checking weather forecasts to anticipate snowfall.
2. Before it starts snowing, ensure the sidewalk is clear of debris and snow.
3. Spread a thin layer of salt evenly on the surface of the sidewalk. You can use a handheld spreader or a shovel to distribute the salt.
4. Focus on problem areas such as slopes, icy patches, or areas with less sunlight exposure.
5. It is crucial not to overuse salt, as using excessive amounts can harm plants, damage concrete, and potentially contaminate nearby water sources.
6. After the snow melts, shovel any remaining slush or ice off the sidewalk, if necessary.
7. Store salt in a dry place for future use.
Remember to check local regulations and guidelines regarding the use of salt on sidewalks, as some areas may have specific rules or restrictions to protect the environment.
