Write the equation for the Equilibrium constant, K, for the equilibrium between [CoCl4] 2– and [Co(H2O)6] 2+ .
Homework Answers
The reaction happens in accordance with the Le-Chatelier's principle. The main species involved in the reaction is cobalt(II)chloride Or CoCl2, which usually comes in forms of hexahydrate, CoCl2. 6H2O. When dissolved in water both CoCl2. 6H2O will produce the complex ion [Co(H2O) 6]2+.

Aqueous solutions of Co2+ salts are pale pink. They contain the complex ion [Co(H2O)6]2+. Addition of concentrated HCl results in a profound colour change to dark blue, due to formation of [CoCl4]2–. The main absorption bands of [Co(H2O)6]2+ and [CoCl4]2– occur at 19400 cm–1 (e ~ 10 M–1 cm–1) and 14700 cm–1 (e ~ 1000 M–1 cm–1), respectively. (i) Explain the difference in the transition energies between the two complexes. (ii) Using a qualitative molecular orbital diagram, explain why the...
