Equilibrium and Le Chatelier Principle
According to Le Chatelier's principle: What is going to happen to the color if you add more CuCl42- and why? The Kc is the equilibrium constant, the large the number the more product is favored. System 1: Cu²+(aq) + 4C1 (aq) = CuC142-(aq) Blue/Green Green/Yellow Kc or lc [CuCl2-] [Cu2+][C1-]4 O It will turn more Blue/Green and since you are adding extra chlorine ion O It will turn more Green/Yellow and since you are adding...
