What effect does salt have on rust?

salt doesnt have as much effect on rust.... where rust comes from is oxygen reacting with the iron in your vehicle....\n\nso when water (H20) comes in contact with iron (Fe) it creates iron oxide...rust(FeO2)

Oxygen in the atmosphere reacts with iron to oxidize it in what is called a redox reaction (oxidation/reduction).  The redox reaction is defined by the exchange of electrons--uncharged iron will lose two electrons to an oxygen molecule, creating iron oxide.  Water quicken rusting by serving as a catalyst.  Dissolved oxygen in the water reacts, and as the water dries, the oxygen becomes increasingly concentrated.\n\nShips will prevent wide-spread rusting by creating what is called a "sacrificial anode."  You might know the names anode and cathode from the ends of a battery.  Batteries function by employing two seperate redox reactions, where one end corrodes to release electrons, which travel to the other end and react with metal cations in solution, turning them to a solid metal.  In the case of ships, the corrosion of iron is prevented by creating a sacrificial anode out of something even more reactive than the iron (usually magnesium, if memory serves).  The corrosion of the magnesium releases excess electrons in the iron, which delays corrosion of the iron--oxyegn can grab the free electrons created by the corrosion of magnesium without needing to corrode the iron.\n\nI would imagine that the quickening of the rusting process cause by a scratch in the tin is due to the fact that the corrosion becomes concentrated in a single place.  The scratch likely serves as the "sacrificial anode" for the rest of the can.

If the rim is all aluminum or all chrome it won't rust if they are just plated with aluminum or chrome then it depends if the surface metal was scratched off.

Theonly possible effect it could have is on urinary tract infections. The human body itself mainatains a constant salt balance regardless of dietary salt intake.

A metal's corrosion (rusting) rate depends on its chemical properties. Some metals just take longer than others to corrode. Keep in mind that most metals have very high melting temperature, so in general high temperature doesn't contribute to the corrosion of a piece of metal just sitting in a damp space. For temperature to be of concern, it has to be around 700 degrees Celsius.\n\nI don't know much about your experiment, but you might not be using an appropriate metal sample. Most commonly found metals come with coatings or contain chemical inhibitors to prevent corrosion. Think about bikes sitting in outside in a humid (moisture-rich) environment. Manufacturers have to coat the metals to prevent this corrosion, or else no one would buy their product. This is the case with most metals. So if you just picked up something laying around the house and tried to corrode it, your experiment might not be successful. You should also be aware that only ferrous (iron) alloys rust, and the particular metal you tested might be something else.\n\nGo to google and type "rusting metal" (without the "s). The first four sites have lots of info.\n\n*It wouldn't rust in the freezer because there's no moisture in the freezer.

Rust is a chemical reaction involving iron and oxygen.  Melting metal is simply a physical reaction changing the state of its matter, so melting the metal wouldn't get rid of the rust to the best of my knowledge.  IT might however make it easy for you to seperate the rusted and non rusted parts of the metal, but then again it might make it a total mess lol

water and oxygen are 2 things which cause rusting..in this case there is lots of water and lots of oxygen in the boiling water plus there is the catalyst of heat..\n\nbut by painting it with aluminium paint the surface of alumnium reacts to form an unreactive strong layer of AL2O3 this protects alumninium from furtherly rusting and the iron or steel behind the aluminium>>>plus they usually do this instead of using completely aluminium pipes because its more economic to use steel and paint with aluminium instead of making aluminium pipes plus steel is much stronger

Rusting is a chemical process that, can take place in metals exposed to the atmosphere. Not all metals however rust. Rusting is common with the metal, iron. Certain conditions in the air around a metal have to be present for iron to rust. Iron rust which, generally appears brown, is itself a chemical compound quite different from the iron itself. The rusting of iron can be prevented. In towns and large cities where iron sheets are used for roofing houses, rusting can also take place if the iron sheets are not protected from rusting. \n\nRust is the common name for a very common compound, iron oxide. Iron oxide, the chemical Fe2O3, is common because iron combines very readily with oxygen -- so readily, in fact, that pure iron is only rarely found in nature. Iron (or steel) rusting is an example of corrosion -- an electrochemical process involving an anode (a piece of metal that readily gives up electrons), an electrolyte (a liquid that helps electrons move) and a cathode (a piece of metal that readily accepts electrons). When a piece of metal corrodes, the electrolyte helps provide oxygen to the anode. As oxygen combines with the metal, electrons are liberated. When they flow through the electrolyte to the cathode, the metal of the anode disappears, swept away by the electrical flow or converted into metal cations in a form such as rust.\n\nFor iron to become iron oxide, three things are required: iron, water and oxygen. Here's what happens when the three get together:\n\nWhen a drop of water hits an iron object, two things begin to happen almost immediately. First, the water, a good electrolyte, combines with carbon dioxide in the air to form a weak carbonic acid, an even better electrolyte. As the acid is formed and the iron dissolved, some of the water will begin to break down into its component pieces -- hydrogen and oxygen. The free oxygen and dissolved iron bond into iron oxide, in the process freeing electrons. The electrons liberated from the anode portion of the iron flow to the cathode, which may be a piece of a metal less electrically reactive than iron, or another point on the piece of iron itself.\n\nThe chemical compounds found in liquids like acid rain, seawater and the salt-loaded spray from snow-belt roads make them better electrolytes than pure water, allowing their presence to speed the process of rusting on iron and other forms of corrosion on other metals.

Most corrosion is on the outside so it really doesn't make a difference, hot or cold. What determines corrosion is the \nenvironment outside of the pipe.

I will assume that "salt" is referring to sodium chloride, NaCl.  The solubility of NaCl increases with increasing temperature and decreases with decreasing temperature.\n\nSince you are starting with a saturated solution (meaning that it contains the MAXIMUM amount of NaCl at that temperature) and you are cooling the solution to 20oC from 60oC, the cooler solution will not be able to keep the NaCl dissolved and you will observe small crystals of NaCl precipitating from the solution.

sodium chloride or salt

Yes it does. Corrosion is when the metal oxidises.

nothing, the salt water will NOT react with iron, however the rion will just replace a few of the ions of the mineral and still probally nothing will happen

actually, stainless steel can corrode.  There are different grades of stainless based on the amount of nickle, chrome and other additives that protect it from oxidizing, however, if those additives are in too small amounts (as in low grade stainless), it can rust.  It'll still be slower than regular steel but it is not in vincible.

Slow oxidation of iron into its hydrated oxide by oxygen of the air in the presence of moisture is known as rusting.\nA flaky browncoating of hydrated iron contining variable number of water moleculesis formed on the surface of the iron.This flaky coating crumble from the surface of iron making its fresh surface available for attack of atmospheric oxygen and moisture,Rusting is therefore oxidation of iron ,\nScrews are made of galvanised iron.

The salt melts the ice.  The car goes over the water, gets splashed. Salty water wets the car.  Water evaporates leaving the salt on the  car.  Everytime there is some moisture on the air, salt re-dissolves and attacks the metal.  This will continue until you wash your car.\n\nConclusion.  If you leave in snow country where salt si spread wash your car during the winter frequently.
