SBI4U Homework

Show drawings of the following:

  • A grain of salt made of six formula units of NaCl that has just been placed in distilled water (dH2O)
  • The grain of salt from the description above as it would be after it is half dissolved
  • A solution if the grain of salt was fully dissolved

Remember to consider how the water molecules orient themselves around the dissolved sodium ions and the dissolved chloride ions.

What force of attraction holds the ions in the grain of salt together?
