I will try my hardest to answer this question because i have just done a question like this in my GCSEs.
Because tap water is not as strong as salt water the nails coating (or outside) reacts slower. But because salt water is stronger and contains more density, it takes away more coating (or outside) quicker, as the nail reacts.
thats all i can say!
vinegar because it is acidic
Coke.
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.
it rusts faster when it is damp cause the moisture of the damp and oxygen when they meet they create rust
A spoon
An iron nail will rust slowly in distilled water when that water has dissolved oxygen. If you get rid of the oxygen by boiling and keep it from getting back in then the iron nail will not rust at all.
Chemical change, oxygen binds with iron.
It rusts faster in salt water.
a penny
Bleach rusts faster i know this because I did a science experiment on this and bleach was first to begin first
Salt water.
i think vinegar will make a nail rust faster because vinegar will makes the mental with iron in them.
it will rust faster ing vinegar,then orange juice coke and water..............look out here we go
