Why can table salt (NaCl) dissolve easily in water?
  a. Water can add electrons to the sodium ion.
  b. Water can form covalent linkages with salt molecules.
  c. Water can remove electrons from the chloride ion, which causes the latter to dissociate from the sodium and
  dissolve.
  d. Water is polar and salt is nonpolar. Nonpolar compounds are more soluble in polar solvents because they are
  able to form strong covalent bonds that result in a breaking up of the molecule being dissolved.
  e. The partial positive charge of the hydrogens in the water molecule can associate with the negative charge of
  the chloride ion, and the partial negative charge of the oxygen of the water molecule can associate with the
  positive charge of the sodium atom.
