When NaCl (sodium chloride, table salt) dissolves in water, the NaCl molecules break apart. The hydrogen atoms form hydrogen bonds (I think?) with the Cl- ions. What is the name of the bond between the oxygen atoms and the Na+ ions?

    $\begingroup$ There is no molecules in solid sodium chloride. There is a series of alternating $\ce{Na+}$ and $\ce{Cl-}$ ions alined on the three axes Ox, Oy and Oz. When dissolved in water, these ions are simply separated without any molecular breaking. $\endgroup$

  • $\begingroup$ Hydrogen bonding is mainly used for polar covalent bonds and not for free ions. $\endgroup$ Commented Aug 17, 2023 at 17:09

    $\begingroup$ Both the sodium cation and chloride anion will be surrounded by polar water molecules forming a "coordination sphere." However such + and - groups can be attracted to one another in concentrated solutions and form an ion pair. Ion pairing is one reason that activities differ from concentrations. $\endgroup$
