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 0.00113 mol Ni(NO3)2 and 0.484 mol NH3 are dissolved in a total volume of 1.00 L.
Calculate the concentration of Ni(H2O)62+ ions at equilibrium in the solution formed.
