Rust is essentially oxidation, or a chemical interaction involving oxygen. When oxidation occurs in some elements, a thin film is formed as a result--such as the green layer that copper acquires. Other elements, such as iron, show rust as evidence of oxidation. If iron--or metal related to iron--is exposed to an environment both oxygen-rich and friendly toward the catalyst, then the oxidation process will begin. Molecules of iron at the surface of the iron object will exchange atoms with the oxygen in the air, and what atoms are left will form a new substance, the reddish-brown rust.
Oxidation is an electrochemical process that acts somewhat like a battery, exchanging small amounts of electricity. Like batteries, a solution helps this process by allowing electrons to move more easily between the two elements, and also like batteries, different solutions work better than others. Water takes some of the atoms and changes them into a light form of acid as the oxidation process continues, which helps metal rust even faster.
This acidic transformation occurs with pure water, but when the water is already salty it starts out as a minor acid and becomes an even more powerful electrolyte, facilitating the rusting process. There is then a hierarchy in the rust process. Rust does not easily form in dry climate, but in a wet climate the oxygen can access the metal more easily through the water vapor, and rust occurs much faster. Pure water forms an acidic solution and allows the oxidation process to happen more easily, and salty water works even better since it is already a catalyst. Prime rust conditions occur when the metal is regularly exposed to salt water and air.

Does iron nail rust faster insltor fresh water2. materials:two nail,two cup,salt water,fresh water,3. Hypothesis.I think that a nail rust faster in salt water because of the chemicals in the salt.4. Procedure:inde variable:same nail and fresh and salt waterdep variable:how many days will it takecon varable:size of nail,different waterstepsgather my m
Salt water does make nails rust faster than non-salted water, because when salt is added to water, it will rust the top layer of the nail, and then make the nail basically shed its top layer. Then the salt will rust that layer, and this process continues until the whole nail is rusted. Normal water can only really rust the top layer, and can't get to the rest of the nail.
Zinc will corrode in vinegar faster than salt water
How long will it t take a quarter to rust in fresh water
ANSWER:oxygen and water
Iron will rust more quickly in salt water than fresh freshwater. The salt in the water accelerates the corrosion process.
Modern coins cannot rust, as they are not made of iron.
salt will rust the coin faster thanfresh water
Liquids do not rust, iron does, rust is Hydrated Iron (III) oxide, so the only substance which can rust iron is water
Salt water speeds up the rate of rust. Seaside houses often have rusted fences and decorative iron work whereas the same iron work lasts much longer inland.
Salt water.
coke will make it rust faster
Salt water contains Na+ & Cl- ions which are highly reactive with iron to form FeCl2 .So iron rust faster in salt water.
Yes they will.
It rusts faster in salt water.
water
Iron and steel rust when they come into contact with water and oxygen. They rust faster in salty water or acid rain
