(4 pts) Describe what you would expect to observe at the macroscopic level when sodium chloride (‘salt’; NaCl) is placed into water and stirred. Explain what you think is occurring at the molecular‐level with the particles that accounts for the macroscopic observations you describe. You should use precise terminology in this explanation to distinguish whether you think the particles are molecules, atoms, and/or ions.
