it depends but i will take longer than fresh water
Yes, salt can evaporate from water. When water evaporates, it leaves behind the salt, which does not evaporate.
Put 2 cups outside on a sunny day. One with salt water and one with regular water. Check on them every 5 minutes or just watch them. Then you time how long the salt water took to evaporate compared against how long it took the regular water to evaporate. Then you'll have your answer.
Epsom salt is a stable compound that does not easily evaporate. It can only evaporate along with water if a solution of Epsom salt and water is left to dry out, which could take days to weeks, depending on the conditions.
Salt water will evaporate faster.
Water is water. It will evaporate no matter what is it. The real question is whether or not the chemicals or salt will evaporate with the water or not. The answer to that is no. The salt/chemicals will stay in the container.
If you boil it, the water will evaporate. If you leave it boiling long enough, you should only have salt left.
Evaporate the water.
Salt water will evaporate first. Salt takes up space so to speak and there's less "water" to evaporate and so it seems to evaporate faster.
Dont get me wrong, but you seem to be asking how to separate salt from water. I think if you evaporate water, the salt cannot evaporate, and it stays behind. However, if the light is really hot, it will evaporate the salt along with the water. (Example: If you put salt and water in a dish and hold it on top of a lit candle, the light is hot enough to evaporate water, but not hot enough to evaporate salt.
When ocean water evaporates, the salt does not evaporate with the water. The water molecules evaporate, leaving the salt behind. This is why seawater is salty, as the salt remains in the ocean as the water evaporates.
no
Water is evaporated from the salt water.
