Verified step by step guidance1
Understand that the problem is asking for the name of the process where water molecules surround ions during dissolution.
Recall that when ionic compounds dissolve in water, the water molecules interact with the ions to stabilize them in solution.
This interaction involves water molecules surrounding the ions, which helps to separate and disperse them throughout the solution.
The specific term for this process is 'hydration,' which refers to the association of water molecules with ions or molecules.
Note that other options like sublimation, precipitation, and oxidation refer to different chemical phenomena unrelated to the process of ions being surrounded by water molecules.
