Metal cations in solution are complexed to H2O molecules and exist as hydrated ions. For example, Ni2+ complexes to form the hydrated ion Ni(H2O)62+. Metal cations are also able to complex to other ligands, such as NH3. An aqueous solution is prepared in which 0. 00153 mol Ni(NO3)2 and 0. 353 mol NH3 are dissolved in a total volume of 1. 00 L. Kf for Ni(NH3)62+ is equal to 5. 5 × 108.
Part 2) Write the expression for the dissociation constant needed to determine the concentration of Ni(H2O)62+ ions at equilibrium in the solution formed in Part 1.
Kd = [Ni(NH3)3 + ][no] [NH] 6
This is what I put for part 2, but it is not right.
Part 3) Calculate the concentration of Ni(H2O)62+ ions at equilibrium in the solution formed
