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.
Because salt water has higher density
Salt water lowers the freezing point of water, making it harder for the water to freeze. This is because the salt disrupts the formation of ice crystals. As a result, salt water can stay frozen longer than plain water at the same temperature.
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
Melted ice water is beneficial for plants because it is free from the chemicals often found in tap water, such as chlorine and fluoride. This can help reduce the risk of toxicity in plants and improve soil health. Additionally, melted ice water is usually at room temperature, which can be more gentle on plant roots compared to cold water straight from the tap.
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.
