HW 6D.11

I understand that for part e, Al3+ is a small highly charged transition metal therefore it attracts water molecules. However, how do we know that it binds to 6 H2O molecules?

It seems that the Al3+ hybridizes its s, p, and d orbitals to form 6 hybridized orbitals. The reason why it's 6 is because that's the maximum number of H2O molecules that can fit around a Al3+ ion, and by having the maximum number of bonds, it is the most stable.

Here is a good resource if you want to look more into it, but I don't think we are expected to figure that out without previous knowledge.
