The particulate diagram represents all the solute particles in separate aqueous solutions of \(\text{MgCl}_2\) and \(\text{NaOH}\) before the solutions are mixed. Each solute is completely dissociated. When the solutions are mixed, insoluble \(\text{Mg(OH)}_2\text{(s)}\) forms, while \(\text{Na}^{+}\text{(aq)}\) and \(\text{Cl}^{-}\text{(aq)}\) are spectator ions.

Which particulate representation could show the contents of the container after precipitation is complete?
