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.
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)
Yes, saltwater is corrosive for Iron and will cause Iron to rust.
Yes.
Iron present in the nail oxidizes in oxygen to form the iron oxides
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.
It either cleans the nail, or makes the nail have rust.
Well I did and experiment for 30 days with 7up and an iron nail and it did not rust.
They combine to form rust. You might be able to guess from what's combining that "rust" is apparently an iron oxide.
salt water would rust a nail in roughly 2 hours as salt has a fast reaction to metals (nails).
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.
it can rust it reacts with atmosphere and reacts with iron oxide then it get rusted
