What metal corrodes with salt water?

All of them, to a greater or lesser degree, depending on their position in the "Electromotive Series of Metals," also known as the "Galvanic Series of Metals." This is a list of metals in order from most to least reactive in sea water. If there are two metals near each other in salt water, the one which is the more reacive (a.k.a. "least noble") will corrode, thus protecting the other metal. This is why ships often put chunks of zinc (called "zinc lozenges") near the propeller---without the zinc, the steel hull would corrode very quickly as it is more reactive than the bronze propeller. The zinc is more reactive than steel even, so it will do all the corroding and the hull is protected. Of course you have to replace your zinc lozenges periodically, as they will corrode away to nothingness eventually. Here is a simple one: From Most Noble (Protected Metals) to Least Noble (Corroded Metals): Mercury Vanadium Gold Silver Monel Nickel Passivated Stainless Steel (rare type) Copper Brass Tin Lead Active Stainless Steel (most common type) Cast Iron Steel Aluminum Zinc Magnesium You see that zinc is quite low on the list, and will corrode first and thus protect everything above it. Stainless steel is higher than ordinary steel---it stays stainless by forcing everything below it (like ordinary steel) to do the corroding. However, if you put stainless steel alongside nickel in salt water, the stainless will do the corroding and the nickel will be protected. Fancier lists include more metals and alloys of different metals.

Does the air in Salt Lake City have salt in it?

Not really. Unlike places that are near the ocean, Salt Lake City's air doesn't contain the salt that corrodes metal. This is because the air is so dry that the water from the Great Salt Lake doesn't really evaporate into the air and hover there like it does in coastal cities.


How does a salt water system work?

the low levels of salt in the water pass through a bunch of platelets that are electrically charged. the reaction of electricity passing through salt water is chlorine. not very indepth but that's the jist of it. it has been in use for years in australlia. however, they don't' have ladders in their pools. the salt water corrodes metal rapidly. ask your supplier about an electromagnetic disc for your skimmer basket to prevent this.

How does metal rust in water?

You must add salt in water because water molecules are closely bonded then salt helps in breaking water molecules and after adding salt water is able to penetrate inside the metal then the metal 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.
