Easy. Find two things made from the same kind of iron. (Old-fashioned cut nails are available at hardware stores, and they're iron.) Mix up a batch of salt water, and pour it into a bowl. Pour the same amount of fresh water into an identical bowl. Then add the same number of nails to each bowl. Every day take a picture of the two bowls side-by-side.
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 that contains oxygen then the oxidation process will begin. Molecules of iron at the surface 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 thanothers.
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. Prime rust conditions occur when the metal is regularly exposed to salt water and air.

Does iron rust faster in vinegar saltwater or freshwater?
Zinc will corrode in vinegar faster than salt water
Does saltwater make metal rust faster than unsalted water?
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.
What two substances are need to rust Iron?
ANSWER:oxygen and water
How are the density of wood and iron the same?
iron is more dense then water and wood is less dense then water. iron sinks because it is heavier then the density of water. wood sinks because woods density is lighter then the density of water.
Will iron rust faster in salt water or fresh water?
Iron will rust more quickly in salt water than fresh freshwater. The salt in the water accelerates the corrosion process.
Why do coins rust faster in salt water than fresh water?
Modern coins cannot rust, as they are not made of iron.
Does iron nail rust faster in salt water or fresh 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.

What type of water rusts steel faster salt water fresh water or refrigerated water?
Salt water will rust steel faster than fresh water or refrigerated water. This is due to the corrosive properties of salt, which accelerates the oxidation process that leads to rust formation on steel surfaces.
What water makes iron rust faster?
Salt water.
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.
Does sound go faster through water or iron?
Sound travels faster through iron than through water. In general, sound travels faster in denser materials, such as solids like iron, compared to less dense materials like liquids such as water.
Why is rusting of iron faster in rainy days?
rusting of iron is faster in rainy days because water is responsible for the rusting of iron i.e the presence of oxygen
Why does iron rust faster in salt water than in tap water?
Salt water is a more conductive solution than tap water, which accelerates the electrochemical process of iron oxidation (rusting). The chloride ions in salt water can also react with the iron to form more rust at a faster rate compared to tap water.
What added factors can cause iron to rust faster?
water
Which warms up faster when heat is applied iron water sand or wood?
Iron has the lowest specific heat, so it will heat up faster.
