5. (6 points) Reduction potentials can be easy to measure, and they can be used to determine solubility products. Calculate the Ksp of nickel hydroxide, Ni(OH)2, at 25 °C. Write your answer in the box. Hint: A solubility product is the equilibrium expression for a solid dissolving in water: Ksp = [Ni²⁺][OH⁻]² = 1 Ni(OH)2 (s) → Ni²⁺ (aq) + 2OH⁻(aq) Ecell -0.762 -0.762 0.025693 11 = n 0.025693 N Ink 0.0128 • Inks knk 59 S -59 53 3 Ink
