Complete the following sentence: "When ionic compounds dissociate in water, each ion is surrounded by a sphere of hydration: ___
Archy [21]

Answer:

Cations, Oxygen, Anions, Hydrogen

Explanation:

Water molecule is polar (meaning it has dipoles). The oxygen having a higher atomic mass attracts most of the electron cloud of the molecule becoming partially negatively charged and leaving the hydrogen end to be partially positive.

An Ionic compound is one between two atoms where one donates its electrons to the other for both to achieve stable configuration. The two atoms, therefore, become charged and are bought together by electrostatic forces.

When an ionic compound is put in water, it dissociates into its ions (anions and cations) They attract and repel with the polar water molecules depending on their charges. The anions (negatively charged ion) are surrounded by water molecules with the hydrogen ends and the cations are surrounded by water molecules with the oxygen ends.
