the question of science i had
as increased ammounts of salt are thrown on roads in winter
rusting of the metal parts of a bicycle may increase
because ????
bid on red grind |

| No. Rust is a form of oxidation, and regular salt, (NaCl) does not contain any of Oxygen. |

| Salt doesn't cause oxidation. It might be because there's more water(since salt prevents ice/snow from solidifying) and therefore a potential cause of the faster rate of oxidation on iron/metals. |

More Technical Definition:
NaCl is used to cause the freezing point of water(H2O) to increase therefore allowing roads(where typically used) to be unfrozen to a certain extent. When NaCl is added into water, the water is no longer entirely composed of water molecules therefore making freezing more difficult as there is something in between the molecules themselves. The snow/ice would become water and the water would react with the iron or copper or etc to create iron/copper/etc. oxide which is known as rust. The salt water solution acts nearly the same as pure water on metal, so it would not make much of a difference.
Simple definition:
Salt causes snow to melt. Water from melted snow rusts bikes and stuff. |
