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.
i looked this up on another website and it said that pennies rust faster in saltwater. but i don't know why.
but it dont
why dose a penny rust faster in salt water than in vinegar
It rusts faster in regular water
saltwater
Because salt is a corrosive chemical.
because of the oxide nuetrons combining with salt and the electrons more quickly dieing from salt
Pennies don't rust; they're copper. They corrode. The phosphoric acid, carbonation and salt in soda will corrode a penny faster than the other liquids.
Because the ion chloride (Cl-) from salt is very corrosive.
In saltwater. In saltwater.

Zinc will corrode in vinegar faster than salt 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.

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.
Yes, it actually rust's faster than in normal water.
Actually, vinegar and saltwater makes it rust... it happened to me...

The saltwater air causes things to rust faster than non-saltwater air.
