The combination of moisture, oxygen and salt, especially sodium chloride, damages metal worse than rust does. This combination corrodes, or eats away at, the metal, weakening it and causing it to fall apart. Saltwater corrodes metal five times faster than fresh water does and the salty, humid ocean air causes metal to corrode 10 times faster than air with normal humidity. Bacteria in ocean water also consumes iron and their excretions turn to rust.

Why does saltwater make a nail rust?
It's not just saltwater that makes a nail rust, even water makes a nail rust. Rust is simply oxidation, it happens when oxygen comes into contact with something and creates a chemical reaction and creates "oxides". Iron + oxygen = Iron oxide (red rust on steel)
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.
How long would saltwater rust a nail?
Saltwater can cause a nail to rust relatively quickly compared to freshwater, usually within a few hours to a day, due to the high concentration of ions in the saltwater which accelerates the oxidation process on the metal surface.
Why do metals rust more in saltwater?
Yes, saltwater is corrosive for Iron and will cause Iron to rust.
Does iron rust in saltwater?
Yes.
When a nail rust iron from the nail combines with oxygen from the air to form what?
They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.
Why does an iron nail rust?
Iron present in the nail oxidizes in oxygen to form the iron oxides
What makes iron rusts in distilled water?
An iron nail will rust slowly in distilled water when that water has dissolved oxygen. If you get rid of the oxygen by boiling and keep it from getting back in then the iron nail will not rust at all.
What happens to nail after heating?
It either cleans the nail, or makes the nail have rust.
Why does a rusty nail weigh more than the original nail?
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
Is rust forming on an iron nail is that a mixture?
Rust forming on an iron nail is a chemical reaction rather than a mixture. Rust is a compound made up of iron oxide that results from the reaction of iron with oxygen and water in the presence of air.
Why a rusty nail weighs more than the original nail?
