When an ionic compound dissolves in water, the cations and anions remain connected to each other with their ionic bonds, and the combined unit is surrounded by water molecules. This is a property of nonelectrolytes. In the case of strong electrolytes, the water is separated into H2 and O2 gases. The cations and anions separate and each ion is surrounded by water molecules, which is also a property of strong electrolytes. Additionally, the cations and anions can chemically react with the water, resulting in an oxidation-reduction reaction.

The partial charges in this water molecule occur because of slightly negative charges on the oxygen atom and slightly positive charges on the hydrogen atoms. This is due to the unequal sharing of electrons between hydrogen and oxygen in the covalent bond. The unequal sharing of electrons allows the oxygen atom to achieve a more stable configuration than the other partner in the bond.

The partial negative charge in a molecule of water occurs because ________. the oxygen atom has two pairs of electrons in its valence shell that are not neutralized by hydrogen atoms the electrons shared between the oxygen and hydrogen atoms spend more time around the oxygen atom nucleus than around the hydrogen atom nucleus the oxygen atom donates an electron to each of the hydrogen atoms one of the hydrogen atoms donates an electron to the oxygen atom
