Question

Anhydrous AlCl₃ is covalent. From the data given below, predict whether it would remain covalent or become ionic in aqueous solution. (Ionisation energy for Al = 5137 kJ mol⁻¹; $\Delta H_{hydration}$ for Al³⁺ = –4665 kJ mol⁻¹; $\Delta H_{hydration}$ for Cl– = – 381 kJ mol⁻¹.)

Answer 1

ionic compound and remain same
