Formation of Water Shells Around Ions
In solution, water molecules form a "shell" around ions. This model illustrates how ions solvated by water molecules move. Note, however, this 2D model does not depict the real shell structure, which in reality is 3D.

Water is a great solvent, but all substances that water can dissolve must
be either polar or ionic (either positively or negatively charged). The
polar water molecules attract charged particles and push out non-charged
particles. Water is attracted to itself, to other polar molecules, ionic
substances, and to polar substances.
