With salt, because salt has a lower boiling point than water.
Sink water or water without salt.
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.
salt crystles
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.
Salt. You get salt flats.
The process of rock salt evaporating is called evaporation. Evaporation occurs when water evaporates from the salt crystals, leaving behind only the salt.
the water evaporates and the salt stays
No. Water with salt evaporates slower than water without salt. The reason, is because water with salt raises the boiling point of water, therefore meaning it requires more heat to evaporate. Water normally evaporates at all temperatures above freezing; the higher the temperate, the faster it evaporates. Plain water will boil at 212 degrees Fahrenheit, whereas a mixture of 2 tablespoons salt to 2 cups of water will cause water to boil at 217 degrees Fahrenheit. The reason is because of an ionic bond caused from the salt. It's harder to break the bond, so more heat is needed which, in the end result, increases the boiling point of water.
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.
After evaporation, the water in the salt solution evaporates, leaving behind the salt that was dissolved in it. This process is known as salt crystallization, where the salt forms crystals as the water evaporates.
Salt remain as a residue.
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.
