What liquid will cause metals to corrode or rust faster

I have decided to base my experiment on quadruplet different types of metals and four different liquids. I exiting be using a penny, nail, piece curry and a chevvy as my four metals. My four liquids will be vinegar, beach, lemon yellow urine and sodium chloride water. To get started, the metal contents should be established. Todays pennies are mostly made of zinc with a thin layer of copper overcoating. A nail is a form of carbon leaf blade or black iron. Paper clips are made from a low grade steel. A needle is made from stainless steel.Examining the liquids and lemon juice is a citric acid. It should have corrosive actions on about of the metals, but not any. I believe that it will not affect this penny, except to vacuous it and ray it. I dont rally it will affect the paper clip either. I think that the only way it will have each affect on the needle or paper clip, will be if they were damaged or scratched. Corrosion would be caused If that were the case. I also th ink in that location were not to be any corrosion to the nail with lemon juice. Vinegar water is used to clean things.Related article Vinegar Battery Review of Related LiteratureI dont think the vinegar will rust a eedle, paper clip, nail, or penny the fastest. There will be a minimum affect on The steel material. The carbonation of water, vinegar and oxygen on the expression will form iron oxide on the nail, the scientific name for rust. Vinegar will remove any corrosion and clean the penny. Bleach is a chloride, like vinegar, I think the affects will be minimal on Most of the metals. Since bleach contains oxygen, it would be most likely the liquids to rust the nail the fastest. The affect on the penny will be more like a cleaning agent, like vinegar and lemon uice, than as a corrosive.I think that salt water will be the best erosive liquid. Salt water will cause corrosion faster because the salt will act as a catalyst steel up the change and erode the materials. I feel it woul d corrode all of the metals. The needle may be the only metal it may not affect it, like some other liquids, it may not rush unless the metal has been scratched deep. In conclusion, I think that salt water will be the most corrosive liquid and the nail made from carbon steel will be the most corrosive metal, in the least amount if time.
