Question
The buffer solution produced at the beginning of the Group III procedure is approximately 1.2 M NH.Cl and 1.0M NH,. Calculate the hydroxide ion concentration in this solution. K, for NH, is 1.8 x 10. The formation constant, K, for Ni(NH.),"? is 5.5 x 10%. Calculate the concentration of free nickel ion in a solution that contains 0.012 M Ni?" and 1.0 M NH3. (Show your work on backside for more room. You might want to consult your gen chem textbook.) Use the hydroxide ion concentration and the nickel concentration you calculated to determine whether Ni(OH); should precipitate from this solution. K, for Ni(OH); is 2.8 x 1016.
