Final answer:
option a,The dissolution of sodium chloride involves ionic bonding and solvation, where water molecules surround and dissociate the individual ions.
Step-by-step explanation:
The interactions involved in the dissolution of sodium chloride (NaCl) are ionic bonding and solvation. Sodium chloride is composed of positive Na+ ions and negative chloride (Cl-) ions. When it is dissolved in water, the polar water molecules surround the individual ions and pull them away from the crystal lattice, resulting in solvation. The positive sodium ions are attracted to the negative pole of the water molecule, while the negative chloride ions are attracted to the positive pole of the water molecule, forming ion-dipole interactions.
The primary interaction during the dissolution process is the ion-dipole interaction, where the polar water molecules interact with the ions once they are dissociated from the lattice. Water molecules orient their negative side toward Na+ ions and positive side toward Cl- ions, leading to the process of solvation or hydration. This stabilizes the ions in solution and prevents them from recombining into a solid.
