Q

Why are solutions of [Al(H2O)6]3+ acidic?

A

Al3+ is small and has a high charge. Al3+ polarises the O−H bonds in the H2O ligands, which weakens the O−H bonds (and allows H+ to dissociate)

Why are solutions of [Fe(H2O)6]3+ acidic?

Q

Why are solutions of [Al(H2O)6]3+ and [Fe(H2O)6]3+ more acidic than solutions of [CuH2O)6]2+ and [Fe(H2O)6]2+?

A

Al3+ and Fe3+ are smaller and have a higher charge than Cu2+ and Fe2+. Al3+ and Fe3+ polarise the water ligands more than Cu2+ and Fe2+, so the weaken the O−H bonds more (and dissociate more H+)
