Suppose that two hydroxides, MOH and M′(OH)2, both have a Ksp of 2.15 × 10−12
and that initially both cations are present in
a solution at concentrations of 0.001 mol/L.
At what pH will the hydroxide precipitate
when solid NaOH is added to the solution?

Which is a characteristic of the electron sea model for metallic bonding? molecular orbitals overlap to produce bands. electrons flow easily between metal nuclei. electrons are in fixed positions in the orbitals. atomic nuclei are arranged in an irregular pattern.
