Question 19 • TX-Chemistry B-CR

Water is called the “universal solvent.” Which statement best explains this description with respect to ionic compounds?

Answer
A
Water can dissociate all ionic compounds through ion-dipole interactions.
B
Water can hydrate many ionic compounds through hydrogen-bonding interactions.
C
Water can dissociate many ionic compounds through ion-dipole interactions.
D
Water can hydrate many ionic compounds through dipole-dipole interactions.

Explanation

Water molecules are polar, so their partial charges attract the positive and negative ions in an ionic compound. These ion-dipole interactions can pull the ions apart and surround them with water molecules, a process called dissociation and hydration. Water dissolves many ionic compounds, but not all of them, so the statement that it can dissociate all ionic compounds is too strong.
