How exactly does road salt cause cars to rust? | Hemmings
22/1/2014· As a side note, sodium chloride isn''t the only road salt available, nor is it the most effective; it''s simply one of the cheapest. Other road salts, like calcium chloride and magnesium chloride, involve more complex molecules that distribute more ions when they dissolve in water, further lowering the freezing point of water.

Corrosion of Eedded Materials - Portland Cement …
Because of concrete’s inherent protection, reinforcing steel does not corrode in the majority of concrete elements and structures. However, corrosion can occur when the passive layer is destroyed. The destruction of the passive layer occurs when the alkalinity of the concrete is reduced or when the chloride concentration in concrete is increased to a certain level.

Fundamentals of Metallic Corrosion in Fresh Water By J.R. Rossum In preparation for this paper, I''ve examined some of the available literature on water well corrosion. I find that much of the material is either wrong, terribly confusing, or else completely misses the
Effect of Sodium Chloride (NaCl) on Rust: Lab Explained | …
In conclusion the aim was achieved and so it was found that placing iron nails in higher concentrations of sodium chloride corrode the most. However once iron is placed in concentrations bigger than 11 percent then the rate of corrosion begins to decrease, as seen with the 30 percent sodium chloride solution.

Aluminium reaction with copper(II) sulfate : chemhelp
8/11/2010· Hello everyone! Yesterday I tried reacting aluminium foil with copper(II) sulfate. Today I checked but no reaction happened. This can be explained by the oxide layer around the aluminium, Al2O3, that can''t coine with CuSO4. HCl can react with this oxide, and the
Aluminum | Encyclopedia
In spite of the fact that aluminum is very active chemically, it does not corrode in moist air the way iron does. Instead, it quickly forms a thin, hard coating of aluminum oxide. Unlike iron oxide or rust, which flakes off, the aluminum oxide sticks tightly to the metal and protects it from further oxidation.
