Dry table salt will not react quickly but it will eventually react. If you coat the brass with a clear finish such as lacquer or Krylon after you polish it there will be practically no reaction indefinitely.
You get a clear glass bowl, and put the salt water in it. Then you put a cup that is below the rim of the bowl in the middle. Next you put plastic wrap over the top, an put it in the sun. This makes it so that the water evaporates and all the salt stays in the bowl, and the freshwater goes into the cup.
Salt cannot be "put in mercury" unless the salt is mechanically restrained. Mercury has a much higher density than salt and does not chemically react with it, so that salt will simply float on the mercury.
In my experience, it can, but it is not recommended in a fish bowl.
nothing, gold does not react at all.
well, Not much but when the water evaporates The salt will still be at the bottom of the cup or bowl. It becomes salty water:P
Nothing, gold doesn't react with sulphuric acid
The sand helps melt the ice. I did an experiment. I put three ice cubes in 1 bowl without ice. The other bowl had salt and ice. The one with salt melted the quickest.
A bowl of steaming hot water and salt, put your face over it and breath in through your nose
Simply get a bowl and put foil in it. Next, put some salt into the foil and put half a cup of hot water and put whichever jewlwery you have and check occasionally.
