The question deals with the lab centering around chemical equilibria and Le Chatelier's principle using microscope techniques. The main focus is on studying the equilibrium of the hexaaquacobalt(ll) complex ion. 1) Predict the direction in which the equilibrium should shift when you add ethyl alcohol to the mixture on Well C-2. Briefly Explain. 2) Briefly explain how your observations do or do not support your prediction. The net ionic equation for the equilibrium involving the hexaaquacobalt(ll) ion in this experiment...
