Molecular Dynamics : Salt dissolves in water 2. Improved.

There is obviously not enough water! ^^ The salt does not dissolve!

so the sodium atom is not separated from chlorine atom by water dipoles ?

[habe36]

Thank you for your comment. You're correct in the case. I guess it would be more time to simulate in order to see the separation.

[maciejwrotek]

@habe36 So, the sodium atom should be separated from chlorine ?

[habe36]

@maciejwrotek, yep. The water molecule slip into NaCl to separate the ions in the room temperature.

[maciejwrotek]

@habe36 i thought metallic sodium reacts with water violently to form NaOH, or is it some kind of electron transfer thing.

[habe36]

@maciejwrotek Okay. The sodium of salt is ionized, Na+. The bonding mechanism of Na and Cl are ionic bonding. The energy level is much lower than metallic sodium. So the salt never reacts like metallic sodium with water.

[maciejwrotek]

@habe36 ok,

[maciejwrotek]

@habe36 so sat is dissolved by whole NaCl particles and later even by atoms?

very nice! i think i get the idea but it would be cool if you could make the water somewhat transparent
