7. If an ionic bond is stronger than a dipole-dipole interaction, how can water dissolve an ionic compound? None of these The ion-dipole interactions of a bunch of water molecules gang up on the strong ionic bond and pull it into the solution. The ions never overcome their interatomic attraction and therefore are not soluble. The ionic bond is weakened by the ion-dipole interactions and ionic repulsion ejects the ions from the crystal. The ion-dipole...

Consider the aqueous solution formed when each of the ionic solids below are dissolved in water. Indicate if the solution will be acidic, basic or neutral. If you indicated that the solution is either acidic or basic, give the pertinent reaction that generates either hydrogen ions H+ or hydroxide ions OH− that involves the appropriate ion. For: MgCl2, KCH3 COO(s), Mg(CN)2(s), NH4 I and LiBr(s)
