Cu^{2+} ion reacts with NH_{3} to form a series of complexes, Cu(NH_{3...
Complex Formation Equilibria:
- Cu^{2+} + 2NH_{3} \rightleftharpoons Cu(NH_{3})_{2}^{2+}
- Cu(NH_{3})_{2}^{2+} + 2NH_{3} \rightleftharpoons Cu(NH_{3})_{3}^{2+}
- Cu(NH_{3})_{3}^{2+} + 2NH_{3} \rightleftharpoons Cu(NH_{3})_{4}^{2+}
Stepwise Formation Constants:
- K_{1} = \frac{[Cu(NH_{3})_{2}^{2+}]}{[Cu^{2+}][NH_{3}]^{2}}
- K_{2} = \frac{[Cu(NH_{3})_{3}^{2+}]}{[Cu(NH_{3})_{2}^{2+}][NH_{3}]^{2}}
- K_{3} = \frac{[Cu(NH_{3})_{4}^{2+}]}{[Cu(NH_{3})_{3}^{2+}][NH_{3}]^{2}}
Overall Formation Constant:
- K_{overall} = K_{1} \times K_{2} \times K_{3}
Explanation:
- The formation of complexes between Cu^{2+} ions and NH_{3} molecules involves a series of equilibria where the Cu^{2+} ion reacts with NH_{3} to form Cu(NH_{3})^{2+}, Cu(NH_{3})_{2}^{2+}, Cu(NH_{3})_{3}^{2+}, and Cu(NH_{3})_{4}^{2+} complexes.
- The stepwise formation constants represent the equilibrium constants for each step of complex formation, indicating the stability of each complex.
- The overall formation constant is the product of the stepwise formation constants and represents the equilibrium constant for the overall complex formation reaction.
- These formation constants are crucial in understanding the complexation behavior of Cu^{2+} ions with NH_{3} and can be used to predict the extent of complex formation under different conditions.
- Cu^{2+} + 2NH_{3} \rightleftharpoons Cu(NH_{3})_{2}^{2+}
- Cu(NH_{3})_{2}^{2+} + 2NH_{3} \rightleftharpoons Cu(NH_{3})_{3}^{2+}
- Cu(NH_{3})_{3}^{2+} + 2NH_{3} \rightleftharpoons Cu(NH_{3})_{4}^{2+}
Stepwise Formation Constants:
- K_{1} = \frac{[Cu(NH_{3})_{2}^{2+}]}{[Cu^{2+}][NH_{3}]^{2}}
- K_{2} = \frac{[Cu(NH_{3})_{3}^{2+}]}{[Cu(NH_{3})_{2}^{2+}][NH_{3}]^{2}}
- K_{3} = \frac{[Cu(NH_{3})_{4}^{2+}]}{[Cu(NH_{3})_{3}^{2+}][NH_{3}]^{2}}
Overall Formation Constant:
