Pure water evaporates faster. This is because the presence of impurities (salt) in the water causes the boiling point of the water to increase.
The greater the difference between the boiling point of a substance and room temperature, the longer it takes for that substance to evaporate. So, pure water takes less time to evaporate.
Of course, other conditions such as temperature, surface area to atmosphere, relative humidity and atmospheric pressure should be constant for both so as to investigate only the effect of salt on the evaporation of water.

How does salt water evaporate?
Salt water evaporates through the same process as regular water. As the heat energy from the sun causes the water molecules at the surface to gain enough energy to escape into the air as water vapor, the salt in the water is left behind. So, the salt water evaporates, leaving behind the salt.
In an activity20 grams of salt are dissolved in 70 grams of water. The water is then heated on a hot plate. When the water evaporates completelyhow much salt will be left?
If the water was pure and had no salt already mixed in it then the same 20 grams of salt would be left, as salt doesn't evaporates on the temperature at which water does evaporates.
Does the concentration of salt decrease when water evaporates?
No, the concentration of salt remains the same even if water evaporates. However, the amount of water decreases, causing the remaining water to have a higher concentration of salt.
Can salt evaporate from water?
Yes, salt can evaporate from water. When water evaporates, it leaves behind the salt, which does not evaporate.
What happens to salt when the water evaporates?
Salt remain as a residue.
When salt water evaporates does it turn in fresh water?
Yes, it does. When the water evaporates, it can not take the salt with it, so if you left a glass of salt water out, when it is evaporated the salt will be on the glass.
What happens to ions after salt water evaporates?
When salt water evaporates, the water molecules dissipate into the air, leaving behind the salt ions. These ions will eventually form salt crystals as the remaining water evaporates completely.

What evaporates faster salt water or corn syrup?
This is salt water.
Why does water evaporate quicker than water?
The warmer water is, the more quickly it evaporates.
When salt water evaporates the salt?
After water evaporation solid salt remain as a residue.
What happens when salt water evaporates and leaves behind salt crystals?
When salt water evaporates, the water molecules in the solution turn into vapor and escape into the air, leaving behind the salt molecules. As more water evaporates, the concentration of salt in the remaining water increases. Eventually, the water is completely evaporated, and only salt crystals are left behind.
What forms when a body of salt water evaporates?
Salt. You get salt flats.
How do you separate water from a salt and water solution?
You boil the salt water so the water evaporates, leaving salt.
Does the concentration of salt decrease when water evaporates?
No, the concentration of salt remains the same even if water evaporates. However, the amount of water decreases, causing the remaining water to have a higher concentration of salt.
Do salt water evaporates faster or do regular water evaporates faster?
Pure water is evaporated faster.
