it takes about 2 weeks
About 2 weeks and leave the salt behind
This depends on many conditions.
This depends on many factors.
fresh water doesnt have salt so it doesnt take as long to have the salt evaporate
This can only be answered by a controlled experiment.

Milk does not completely evaporate, it becomes lactobaccillus

Epsom salt will never evaporate. If the Epsom salts are dissolved in water, the water will evaporate, leaving the dry salts covering the inside of the container.
it depends but i will take longer than fresh water
it takes 1 hour and 30 minutes for a 1/2 cup of salt to evaporate

Water with salt will actually take longer than water without salt to evaporate. This is due to boiling point elevation. If you put a solute into water, it will make it more difficult to boil, and therefore will boil at a higher temperature. Since it takes longer for the salt water to boil, it will take longer for it to evaporate as well

This is not true.
You can tell by taste if water has salt in it, although you should not taste water if there is a possibility that it contains other substances that might be harmful. If you take a small amount of the water and allow it to evaporate, any salt in the water will leave a residue.

Salt wouldn't evaporate, even if you put it in water. If you put salt in water, you could get it out by setting the cup of salt water and waiting until it evaporated. The salt would still be there.
