Kmno4 is more volatile and has lower boiling point unlike Nacl.
evaporation
No, it is dissolution.
The evaporation of water is slow when water is dissolved in salt. This is because of the salt molecules, the salt molecules is the reason for the slow evaporation.
Either evaporation or crystallization.
It is called evaporation. The water becomes a vapor (gaseous state) and is "dissolved" or "mixed" into the air.
Salt is dissolved in a smaller volume of water.
A method is the evaporation of the solution.
Substances that can be separated by evaporation include mixtures of a solid dissolved in a liquid, such as salt dissolved in water. When the liquid is heated, it evaporates, leaving behind the solid substance. Evaporation is a common method used in separation processes in chemistry and industry.
Yes, it is true; this is a method to obtain salt from sea water.
minerals lower freezing point
You think probable to evaporation and crystallization.
EvaporationIf your intent is to have both products--salt and water, then the process is called distillation, in which the water is boiled away and collected.
