Why is salt put on icy sidewalks?
Winter is one season that not all countries can experience. Four seasonal changes are experienced only by countries that areÂ situated along the polarÂ zones of the Earth. While summer, autumn and spring permit individuals to stroll at anytime, winter has imposed several limitations to the activities of the people. This is because sidewalks are typically filled with ice that somehow impedes outdoor activities to be done and causes roads to be unsurpassed by cars. However, science has made it possible for people to travel and prevent any vehicular accidents to take place despite the icy roads and sidewalks.
The application of salt is basically done to allay any onset of accident that may be precipitated by the liquid nature of ice that makes roads and pathways slippery.
Apart from accident prevention purposes, salt is put on icy sidewalks because salt has the capacity to interact with the freezing point of ice, thereby permitting the tires of vehicles to have a firmer grip.
Scientifically, salt triggers the elemental components of water to split into its simplest form, thereby inhibiting the process known as crystallization to occur. When this is initiated, sidewalks become less slippery permitting individuals to walk on icy sidewalks and vehicles to be driven on snow-filled roads without the fear of slipping.
Apart from the salt’s ability to split the components of water, salt also contains properties that come in mixture with the elements of water, making them highly permissive for cars to run on ice.
Therefore, the simple task of placing salt along roads and sidewalks is one essential task that people must adhere to. This does not only make winters merrier but it also makes the season safer and conducive to maintaining one’s health at an optimum level.
