How does salt affect the rate of corrosion and why?

How does salt affect corrosion?

  • Answer:

    Salt increases the waters ability to carry electrons. These electrons take part in corrosion when oxidation and reduction occur. Oxidation is when a substance releases electrons. Reduction is when a substance gains the electrons that were released in the process of oxidation. Since these two processes have to occur together, they are called redox reactions. Salt is hydroscopic. This means that salt attracts water. Since water is needed for corrosion (along with oxygen), salt helps gather that water. Salt increases the water's ability to carry electrons. Electrons are transferred from one substance to another in the redox reactions of oxidation and reduction. This is when a substance loses or gains electrons, respectively. Salt is hydroscopic. This means that salt attracts water. Water is needed for corrosion, along with oxygen.
