  • Describe how a substance can dissolve in water by dissociation, dispersion, or ionization.
  • Describe how the physical properties of a solution can differ from those of its solute and solvent
  • Identify energy changes that occur during the formation of a solution
  • Describe factors affecting the rate at which a solute dissolves in a solvent


  • solute

Online Simulation: Sugar & Salt Solutions

Complete student activity.

Students will:
• Compare the behavior of sugar and salt in water
• Identify sugar and salt as either an electrolyte or a nonelectrolyte
• Draw a particulate representation of salt in water and sugar in water
• Propose an explanation for why a light bulb glows or does not glow
• Extend the definition of electrolytes versus nonelectrolytes to other substances and qualitatively relate bond type to this observation
