Is Cu2+ acidic or basic? What indicator should be used?

Question: Transition metals act as Lewis acids and make hydronium ions, but O2- is also a very strong base, making hydroxides, so is CuO acidic or basic? How is an indicator chosen?

Answer: Since the oxidation state is Cu2+ it is expect to be basic. For indicators, the pK of the indicator should be equal to the stoichiometric point.
