    The positively charged sodium ion (Na+) in table salt is attracted to the negatively charged oxygen-end of H2O molecules more than it is attracted to the negatively charged chloride ion
    (Cl-) of table salt. Therefore, NaCl is easily dissolved into water. Here you see how the oxygens of 6 water molecules are attracted to the sodium, and how the sodium is no longer bonded to its chloride.
