Which one best represents the changes that occur in the solution process?.
Correct. In the presence of water the ions are distributed regularly, surrounded by water molecules. Ion-dipole (water) interactions are not shown.
|
|
Wrong. This animation shows the water molecules
around the solid sample without separation of ions in the aqueous medium.
|
|
Wrong. The animation shows that ions are separated but not water molecules around the ions.
|
|
Wrong. The animation shows that ions are separated from the solid but left in the bottom of the glass. No water molecules around the ions.
