Question

Write the equilibrium expression for the equation. 7. After the water was added to the initial equilibrium mixture, what was the primary cobalt(I) species ? Explain your answer Il combine with cobalt f we add watercreactant) wnh wi aind themory tCoCH 0).a are for med, means initial CO (TI) specics What happened to the mixture when concentrated HCI was added? Explain this using Le Châtelier's principle. adding HCl, means cr ionS are adding. S according to Le Chatelier's &. prinipe reaction will Shtt to reatant nde, and attain new Based on what you observed on heating and cooling the mixture, is the forward reaction in this equilibrium endothermic or exothermic? Explain your answer. 9. as un heating if tuins wards bine co 7-6 10. Rewrite the net ionic equation to include the "heat" term. Part III. Dissalutiu

Explanation / Answer

Answer 10.

[Co(H2O)6]2+ + 4Cl- + heat ? CoCl24-+ 6H2O

The forward equation is an endothermic equation. Heat works as a reactant in this equilibrium. This means that when heat is added, i.e. the solution is being heated, the equilibrium will shift in the direction of the products.
