Ni(NH3)62+ has a Kf of 1.2*109. Write the reaction equation for the formation of the complex ion and the equilibrium constant of the formation expression. Would the reaction mixture be mostly be complex ions or simple ions? (I don’t really understand how to answer the last question)
Using (Kf=1.2×109) calculate the concentration of Ni2+(aq), assuming that it is present as Ni(NH3)2+6, at equilibrium after dissolving 1.62 gNiCl2 in 100.0 mL of 0.20 MNH3(aq).
One millimole of Ni(NO3)2 dissolves in 240.0 mL of a solution that is 0.500 M in ammonia. The formation constant of Ni(NH3)62+ is 5.5×108. What is the equilibrium concentration of Ni2+(aq ) in the solution?
One millimole of Ni(NO3)2 dissolves in 230.0 mL of a solution that is 0.500 M in ammonia.The formation constant of Ni(NH3)62+ is 5.5×108. What is the initial concentration of Ni(NO3)2 in the solution? What is the equilibrium concentration of Ni2+(aq ) in the solution?
Consider a 100.0 mL sample of 0.0200 M Ni(NO3)2.. Then 10.0 mL of 0.300 M NH3 is added. What are the molar concentrations of Ni2+, NH3, and [Ni(NH3)6]2+ at equilibrium? Kf for [Ni(NH3)6]2+ = 2.0 x 108
