20.60 Commercial silver-plating operations frequently use a solution containing the complex Ag(CN); ion. Be- cause the formation constant (K) is quite large, this procedure ensures that the free Ag" concentration in solution is low for uniform clectrodeposition. In one process, a chemist added 9.0 L of 5.0 M NACN to 90.0 L of 0.20 M AGNO,. Calculate the concentration of free Ag" ions at equilibrium. See Table 17.4 for K value.

Write a complete and balanced redox equation for the synthesis of the coordinationcompound. Use iron(II) oxalate (the yellow/orange solid) as a reactant. In other words,complete the following reaction: FeC2O4(s) + H2O2(aq) + ??? → product(s) Assume that the net reaction occurs in an acidic solution: this will make balancing theequation easier. Use the formula of the iron (III) oxalate compound that you found in theliterature to balance the equation ([Fe(C2O4)3]). You must write out the individual half-reactions.
