This new kit is designed to teach students all about oil spills. As you can imagine, it is easier to take apart a mixture like the rocks and sand versus the salt and water. The color black absorbs all frequencies of visible light, which helps the light energize the water molecules which evaporate when they get hot. Will increasing the amount of salt in water effect how slow or fast the water freezes? After a few days salt remains as residue and water evaporates. I would then put two . Would a higher concentration of salt separate more, or would a higher voltage separate more. Because pure water is not good at conducting electricity, however, electrolysis requires the addition of an electrolyte, such as salt or acid. Lowering the temperature further pulls even more water out of the liquid into the ice, leaving the salt outside as separate salt crystals.
