The Charges with Sodium Chloride Are All Balanced-For Every Positive

question 142

Multiple Choice

The charges with sodium chloride are all balanced-for every positive sodium ion there is a corresponding negative chloride ion.Since its charges are balanced,how can sodium chloride be attracted to water,and vice versa?

• A)Dispersion forces come into play as the sodium chloride and water come into close proximity.
• B)Hydrogen bonding in water allows the sodium chloride molecule to be attracted to the water molecule.
• C)As a water molecule gets close to the sodium chloride it can distinguish the various ions and it is thus attracted to an individual ion by ion-dipole forces.
• D)This is not a matter of attraction.Sodium chloride dissolves in water because water provides a medium in which the individual sodium and chloride ions can disperse.
