It's not the color that is significant, its the fresh water that the ice cubes were made with. Salt water is heavier than fresh water so the fresh water floats a top the salt water.
Salt is not evaporated with water and remain as a residue.
yes because it is really cold and plants love it the stem drinks it and it helps it stay alive and think about it would you like warm water or cold water.
Because salt water has higher density
Yes, salt remain as a solid residue.
Evaporating the water will not remove any of the salt. Only the water molecules will evaporate. The salt will stay in the container.
Water is water. It will evaporate no matter what is it. The real question is whether or not the chemicals or salt will evaporate with the water or not. The answer to that is no. The salt/chemicals will stay in the container.
When salt is mixed with water sodium chloride is dissociated in ions.
No, it will be at the bottom - difference in density.

yes
You can separate them by filtration and it would help because when you add water the sand would stay because you would have to add cold water so that the sand will stay and the salt will go through.
If you dissolve the salt and the sand in water the sand will stay beind and the salt would dissappear. But if you want the salt back you can evaporate it off, by boiling the water. (with the dissolved salt in it)
