Pure water and Sodium chloride are both poor conductors of electricity by themselves. However, if sodium chloride crystals are dissolved into the water the solution becomes a good conductor of electricity. How does this phenomenon demonstrate the theory of ionic bonds?

A) The attraction force between ions is not as strong as those between water molecules.
B) It shows that water molecules are necessary for bonding to occur between positive and negative ions
C) It shows that atoms with similar electronegativity values will share electrons equally in chemical bonds
D) Bonds in sodium chloride crystals are made up of charged ions rather then neutral atoms.

No, it is not A. Solid NaCl is made up of positive Na ions and negative Cl ions. In the solid the are not free to move; therefore, solid NaCl does not conduct electricity. When solid NaCl dissolves in water, those ions can separate and thery are free to move in solution. A is not the right answer.

@DrBob222 Dude, you really had to rub it in that they don't know the answer. look at it from their point of view, how would YOU feel if i basically called you stupid for not knowing the answer. i don't care if you say "the student came here to cheat!" that's the TEACHERS fault. i would expect more from a teacher.

I believe it is A

are u even a teacher?/ doctor?

Oh okay I believe I understand what you are saying could it possibly be B due to the fact it states the relationship with positive and negative ions

Uh

No, you don't understand. You're guessing. You had a 1 in 4 chance of getting it right at first and you guessed wrong. Then you had a 1 in 3 chance the second time and you guessed wrong. Now you have a 1 in 2 chance of getting it right. The answer is D. Look at what I wrote. Solid NaCl consists of positively charged Na ions and negatively charged Cl ions. They can't move in the solid state but when dissolved in water the Na ions and Cl ions now are free to move around and then they can conduct electricity. Isn't that what D says: i.e., "D) Bonds in sodium chloride crystals are made up of charged ions rather then neutral atoms."?
