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 0.00139 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. Ions in Solution (2 items) (Drag and drop into the appropriate area below) Do not place spaces in your answer. 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. Calculate the concentration of Ni(H2O)62+ ions at equilibrium in the solution formed.
