A solution is formed by mixing 50.0 mL of 10.3 M NaX with 50.0 mL of 7.2 x 10-³ M CUNO3. Assume that Cut forms complex ions with X as follows:
Cu (aq) + X(aq) → CuX(aq)
CuX(aq) + X(aq)
K₁ = 1.0 x 10²
CuX₂ (aq) K₂ = 1.0 x 10¹
CuX₂ (aq) + X(aq)
CuX3² (aq) K3 = 1.0 × 10³
with an overall reaction.
Cu (aq) + 3X (aq) CuX32 (aq)
K=1.0 x 10⁹
Calculate the following concentrations at equilibrium.
[CuX;2] =
M
[CuX₂] =
[Cut] =[
