A solution is formed by mixing 50.0 mL of 10.0 M NaX with 50.0 mL of 2.0 X 10 -3 M CuNO3. Assume that Cu+ form complex ions with X - as follow:

Cu+(aq) + X -(aq) ⇌ CuX(aq) K 1 = 1.0 X 10 2

CuX(aq) + X -(aq) ⇌ CuX2-(aq) K 2 = 1.0 X 104

CuX2-(aq) + X -(aq) ⇌ CuX32-(aq) K 3 = 1.0 X 103

with an overall reaction

Cu+(aq) + 3X-(aq) ⇌ CuX32-(aq) K = 1.0 X 10 9

Calculate the following concentration at equilibrium.
