In this exercise, parts e and f what does it mean by Al(H2O)6 3+ (aq) and Cu(H2O)6 2+ (aq)?

What is the significance of writing both H2O and (aq)?

Since Al and Cu are both transition metals, when AlCl3 and Cu(NO3)2 react with water, they become hydrated and form coordination compounds or complex ions. Al and Cu in particular like to form octahedral complexes and bind to 6 water molecules. They are both aqueous since they are dissolved in water.
