Basic Water Dissolving Salt Questions

I have a basic question about how water dissolves salt. In the [Khan Academy explanation](https://www.khanacademy.org/science/biology/water-acids-and-bases/hydrogen-bonding-in-water/a/water-as-a-solvent?modal=1), it says that the H and Cl atoms attract each other while the O and Na atoms attract each other.


My question: Does this weaken the bond between Na and Cl within a single NaCl molecule? Or does it weaken the bonds between Na of one molecule and Cl of another salt molecule? Or does dissolution weaken both?




There are no $\ce{NaCl}$ molecules in the solid salt nor in solution. 


In solid salt, there are $\ce{Na+}$ ions, surrounded by 6 $\ce{Cl-}$ ions, while each $\ce{Cl-}$ is similarly surrounded by 6 $\ce{Na+}$ ions. Here is the [Wikipedia picture](https://en.wikipedia.org/wiki/File%3ASodium-chloride-3D-ionic.png) of the structure.


During the dissolution, water molecules reach for a particular ion, oriented toward it by the opposite partial charge of their electric dipole.


$\ce{Na+}$ ions are torn away and wrapped by $\ce{O}$ side of $\ce{H2O}$ molecules, which have a partial negative charge.


$\ce{Cl-}$ ions are torn away and wrapped by $\ce{2H}$ side of $\ce{H2O}$ molecules, which have a partial positive charge.


Ions end hydrated in solution like $[\ce{Na(OH2)}\_n]^+$ and $[\ce{Cl(H2O)}\_m]^-$
