Part 1.
An aqueous solution is prepared in which 0.00113 mol Ni(NO3)2 and 0.353 mol NH3 are dissolved in a total volume of 1.00 L.

Classify the species present in the resulting solution according to their relative amounts. Kf for Ni(NH3)62+ is equal to 5.5 × 108.

Part2.
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.

Part3.
Calculate the concentration of Ni(H2O)62+ ions at equilibrium in the solution formed.
