We have learned in this chapter that many ionic solids dissolvein water as strong electrolytes; that is, as separatedions in solution. Which statement is most correct aboutthis process? (a) Water is a strong acid and therefore is goodat dissolving ionic solids. (b) Water is good at solvating ionsbecause the hydrogen and oxygen atoms in water moleculesbear partial charges. (c) The hydrogen and oxygen bonds ofwater are easily broken by ionic solids.
