A 1.00 L solution contains 3.50×10-4 M Cu(NO3)2 and 2.500×10-3 M ethylenediamine (en). The Kf for Cu(en)22+ is 1.00×1020. What is the concentration of Cu2+(aq ) in the solution?

2 Consider the insoluble compound aluminum phosphate, AIPO4. The aluminum ion also forms a complex with hydroxide ions. Write a balanced net ionic equation to show why the solubility of AIPO4 (s) increases in the presence of hydroxide ions and calculate the equilibrium constant for this reaction. For Al(OH)4, K₁= 7.7x1033. Be sure to specify states such as (aq) or (s). K= Submit Answer 54 $ R % 5 Use the References to access important values if needed for this question. T ?
