After water evaporation solid salt remain as a residue.
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.
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 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.
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.
This is salt water.
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.
Salt. You get salt flats.
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.
You boil the salt water so the water evaporates, leaving salt.
Pure water is evaporated faster.
you boil the water,so the water evaporates and the salt is left behind
When water evaporates from the ocean, the salt remains behind. This process leaves the salt concentration in the ocean water higher than before evaporation.
