Question
Why are solutions of highly charged metal ions such as Cr3+ normally acidic? possible answer but please explainThe hydrated ion Cr(H2O)63+ is a good proton acceptor. The hydrated ion Cr(H2O)63+ can easily lose a proton. The metal ions are normally acidic because they have a positive charge. The anions associated with the ion are normally acidic.

Explanation / Answer
The answer is:
The hydrated ion Cr(H2O)63+ can easily lose a proton.
The Cr(H2O)63+ ion increases its stability by losing a positively charged proton and hence decreasing its overall charge from +3 to +2:
[Cr(H2O)6]3+ => [Cr(H2O)5(OH)]2+ + H+
Production of H+ makes the solution acidic.
