Question
What is the concentration of Cu2+(aq) in the solution?
![A 1.00-L solution contains \(2.00 \times 10^{-4} \, M\) \( \text{Cu(NO}_3\text{)}_2 \) and \(2.40 \times 10^{-3} \, M\) ethylenediamine (en). The \( K_f \) for \( \text{Cu(en)}_2^{2+} \) is \(1.00 \times 10^{20}\).
\[
\text{Cu}^{2+}\,(aq) + 2\text{en}\,(aq) \rightleftharpoons \text{Cu(en)}_2^{2+}\,(aq)
\]
\[
K_f = \frac{[\text{Cu(en)}_2^{2+}]}{[\text{Cu}^{2+}][\text{en}]^2}
\]
In this scenario, copper ions (\(\text{Cu}^{2+}\)) in aqueous solution react with ethylenediamine, a bidentate ligand, to form a complex ion \(\text{Cu(en)}_2^{2+}\). The expression for the formation constant (\(K_f\)) of this complex ion provides insight into the equilibrium state of the reaction, emphasizing the relationship between the concentrations of the reactants and products.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fddc1ec45-98e4-4675-b97b-277ce49cbbd0%2F34d8a70c-2b26-4530-b205-1f7f715fbfdc%2Fj6pc7so_processed.png&w=3840&q=75)
