The correct answer is this: WATER MOLECULES HAVE POSITIVE AND NEGATIVE SIDES.
Water is a polar liquid, this means that, the oxygen and the hydrogen atoms in water molecules has partial charges, the oxygen atom is partially negatively charged while the hydrogen atom is partially positively charged. This arrangement makes it possible for water molecule to be attracted to different types of other molecules, thus it is easy for water to dissolve these substances. Water is described as a universal solvent because of its ability to dissolve a wide variety of substances.
