i know that metal placed in more acidic solution will produce rust faster.but why metal placed near the sea shore will easily have rust?the wind with moisture which contains salt solution,right? however ,i have a problem.When i put the metal in the test tube with sodium ...

chemistry(rusting)
Why metal(eg. iron)placed at aqueous solution will be more easily occur rusting?Is it due to the mobile ions in the aqueous solution ?Please give me an detail explanation ,thank you.
