If you set an ice cube on your kitchen table it will stay frozen longer if it is wrapped in a wet paper towel why?
It depends. If the room temperature is very cold, (about 40 F--4C)it will stay frozen for longer. The towel would be hotter, and would start to melt it and absorb most of the water. If the room is 80 F (20 C) or so, the towel may keep it longer. But, the fact that it is wet REALYY depends. the temperature of the water matters, but regular sink water would keep it melting.

How do you separate salt from the solution?
It is possible to remove salt (chemical name, sodium chloride) from aqueous solution by the evaporation of the water. The water will boil, turning to a gas, and leave behind a dry salt residue. This can be done in the following experiment: Apparatus - Salt solution Tripod Heat (bunsen burner) Boiling dish Method - Pour the salt solution into the boiling dish. Place this dish on the tripod with the heat underneath it. Carefully apply the heat, and keep an eye on the experiment. The water will start to boil, and evaporate away. Once the water has completely evaporated, remove the heat. You are left with salt crystals in the dish.
