steel rusts faster in salt water because there is more oxygen in salt water then in fresh, so if the oxygen stays in long-term contact with the metal it causes it to rust. as for fresh tap water doesn't contain as much oxygen which is harder for the metal to rust as fast

∙ 13y agoRust 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 is both oxygen-rich and friendly toward the catalyst, 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 in pure water. However, if the water is already salty, the transformation starts out as a minor acid and becomes an even more powerful electrolyte, which facilitates the rusting process. There is 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.

Factors that promote rust?
An iron material can easily rust in the presence of air and water. For example if an iron nail is half dipped in water and the rest of the nail is open in the presence of air then the nail can easily rust.
Which metal is kept under water?
I dont think there is a metal stored under water because they react with water and instead are stored in kerosene or oil. Water often corrodes the metal producing rust so i cant think of any metal that would be stored under water.
What is the effect does water have on steel?
Think this through. What is the difference between sea water and freshwater? Salt. What does salt do? Rust or create buildups on metal. What types of metal? Several types including iron and steel.
With what liquid makes a screw rust faster?
vinger makes it rust faster because it has acied in it and tap water does not
How can you turn metal into rust?
Firstly, put metal into water. When these two chemicals engage, the watery metal get's exposed to oxygin which produces rust. So all you need for this is metal and water!
What water will rust the fastest cold or hot water?
warm water will rust metal faster
Does metal rust faster in bottled water or lemon juice?
Metal rusts faster in lemon juice than it does in bottled 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.
Why does heat cause metal to rust faster?
rust is a chemical change it happens when weather is changing. rust jhappens when oxygen and water hit it
What is rust and how fast does rust form in a bowl of water on a nail?
Fe2O3 Iron Oxide time is varying but if the metal is hotter rust occurs faster.
Does the addition of salt make water rust metal any faster?
yes because when the chemichels act up it rust fastes
Can metal rust in juice instead of water?
Yes. The more acidic the juice (citrus juices especially) the faster the metal will rust. Acid is an even more powerful oxidizer than water. Also, juices actually are made of mostly water, which in and of itself would cause metal to rust.
Does metal rust faster in light?
No light evaporates the water rusting the metal, not a lot but enough to make a significant difference.
Which will rust faster metal or steel?
Well steel is metal.
Why is the metal easier get rust when it is near in the seashore?
because its near water the metal reacts with oxygen in h2o so it oxidizes faster
Does tap water or salt water cause metals to rust faster and why?
Most likely salt water. The salt accelerates the rate of corrosion, plus it has the oxygen needed for the metal to rust. Tap water has the oxygen too but with the salt also, it would cause the metal to rust more rapidly.
Which screw will rust faster an iron screw or a metal screw?
of course it is the iron screw because it is made up of minerals that rust faster then metal
