Answer:
Solutions are formed when the water's polar molecules separate the polar molecules of an ionic or molecular compound
Explanation:
Water can hydrogen bond to other molecules due to the O-H bond present in water with partial charges. Water can form hydrogen bonding with other polar molecules. The answer would hence be Solutions are formed when the water's polar molecules separate the polar molecules of an ionic or molecular compound(because polar water dissolves polar molecules in between their interactions).
