Rust iron mixes with oxygen. This happens when water comes in contact with iron because the water conducts the small amounts of current that randomly travel through iron. This in turn causes the hydrogen and oxygen to split and the oxygen is then free to bond with the iron. Salt adds more ions into the water making it a better conductor, so more current passes through producing more oxygen and therefore more rust. Distilled water will not cause rust because H2O alone is not a good conductor.
However with experiments shown distilled water can cause rust on nails because it's properties however you shouldn't take my word for it because I'm just a yr12 chemistry student.
This answer is partly wrong. The oxygen atoms in H20 do not split away from the hydrogen atoms to bond with the metal. The oxygen comes from other sources. There are actually dissolved gases present in the water. The metals obtain the oxygen from the oxygen gas that is dissolved into the water. Additionally, distilled water doesn't make metal rust because to distill water, you boil it away, and boiling water always boils away all dissolved gases that are present in the water. When there is no oxygen in the water the metal is in, it is impossible for rust to form.

Why does iron rust faster in salt water than freshwater?
Because the ion chloride (Cl-) from salt is very corrosive.
Do copper pennies rust in soda or vinegar faster?
Copper pennies will tarnish in both soda and vinegar due to the acidic nature of these liquids. However, they may tarnish faster in vinegar since it is a stronger acid compared to soda. Ultimately, the rate of tarnishing will depend on the concentration of the acid and the duration of exposure.

Do pennies rust faster in saltwater or in fresh water?
Pennies are made of copper and don't rust unless they are the zinc pennies issued in 1942 and 1943. However, zinc will not rust either. The so-called steel pennies minted during World War II were made of steel and coated with zinc. If the penny becomes damaged or if the zinc coating is compromised, the underlying steel will rust if exposed to the proper elements. Pennies do corrode though.

Can rust form on a vehichle under freshwater?
Yes. It actually rusts faster in water, because water is made one third out of oxygen, which you need to make rust. Saltwater rusts vehicles even faster than freshwater does. Cars near the coast get more rust than cars in inland parts of the country.
Does steel rust in saltwater?
Yes, it actually rust's faster than in normal water.
Why houusehold door hinges rust more in the Atlantic provinces of Canada than the rest of Canada?
The saltwater air causes things to rust faster than non-saltwater air.
How does the difference in concentration of saltwater affect the oxidation of a metal?
The more saltwter will make it rust faster.
Does an iron nail rust faster in salt or tap water?
An iron nail will rust faster in saltwater than in tap water. This is because saltwater is conductive and accelerates the rusting process by promoting the flow of electrons between the iron nail and oxygen in the water.
