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.
minerals lower freezing point
Yes, it is true; this is a method to obtain salt from sea water.
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.
Sugar can affect evaporation, as when dissolved in water, is affected by the hydrogen bonding between the water molecules. As it binds a few molecules tighter together in the sugar solution, it may affect evaporation, hindering it very very slightly.
