Question

Why do we put salt on sidewalks when it snows?​

Answer 1

THE REASON IS :-

1.)Salting icy roads and walkways lowers the freezing point of the water that forms ice which leads to melting and prevents falling snow or rain from being able to freeze.

2.)Though salt can be effective, it does have some negative impacts on the environment.

Answer 2

Salt helps in melting of snow as it decreases its freezing point...
