Aluminium chloride (AlCl3) in acidified aqueous solution forms the complex ion [Al(H2O)6]3+. This ion has an octahedral geometry.

Here's the step-by-step explanation:

1. When aluminium chloride is dissolved in water, it reacts with the water to form aluminium hydroxide and hydrochloric acid. However, in an acidified solution, the aluminium hydroxide can't precipitate out.

2. Instead, the aluminium ion (Al3+) attracts the polar water molecules and forms a complex ion.

3. In this complex ion, the aluminium ion is at the center, surrounded by six water molecules.

4. The arrangement of these water molecules around the aluminium ion is in such a way that it forms an octahedral shape.

5. Therefore, the geometry of the ion formed by aluminium chloride in acidified aqueous solution is octahedral.
