Adding NaOH to an aqueous solution containing Ni 2+ results in precipitation of Ni(OH) 2 . The

Question:

Adding NaOH to an aqueous solution containing Ni²⁺ results in precipitation of Ni(OH)₂. The standard potential for the Ni²⁺/Ni couple is −0.25 V and the solubility product K_sp = [Ni²⁺] [OH⁻]² = 1.5 × 10⁻¹⁶. Calculate the electrode potential at pH = 14.
