Now that you know how solutions are formed and some of the factors that will affect the speed at which the sugar and salt you'll be using will dissolve, you should be able to make a good guess as to which one will dissolve faster. The salt has to dissolve into its ions in order to work. Salt reduces the freezing point of water, causing the ice to melt faster. However, the ending could use a little work. It is a matter of bringing warm water into contact with the surface of the cube (this happens with the tap water because of convection) and layering of the cold, colored melt on top of the denser solution (little convection of the bulk fluid here). For a substance to dissolve in water, it must also be a polar molecule, or it must be capable of breaking into polar molecules. Nonpolar substances dissolve in Nonpolar substances. Use the information you gathered when you researched your topic to help you answer these questions. When a sugar solution is slowly frozen? With 45 atoms per molecule, sugar does not separate water molecules as well as smaller, more strongly charged ions, which is why sugar does not reduce the melting point as well as salt. as much as salt because sugar molecules are 6 times larger than salt molecules and therefore there are many more salt molecules in 1 tsp than sugar molecules. Sugar dissolves on ice and interferes with the water molecules. Salt melts ice cubes faster than sugar as it lowers the freezing point of water. TeacherVisionis part of the Sandbox Learning family of educational and reference sites for parents, teachers and students.
