π‘ Solution & Explanation
Step 1: Note that under anhydrous conditions, aluminium chloride exists as a covalent dimer, Al2Cl6. Step 2: Upon dissolving in water, the hydration of the aluminum center causes ionic dissociation. Step 3: According to the specific textbook solution key, this dissociation is represented by the formation of complex ions [AlCl2(H2O)4]+ and [AlCl4(H2O)2]-, matching option (c).
