Brandon Pickett Chemistry 118/Lab 10/1/08 Chemical Equilibrium and LeChatelier’s Principle 1. The initial color of CoCl 2 *6H 2 O is a magenta color. Distilled in water, it is purple with a pink tint. When 3mL of 12 M HCl is added, it turns blue. CuSO 4 *5H 2 O is initially light blue in color. The solid did not dissolve too much in water but the area around the remaining solids was a light blue color. There was some gas formation in the reaction. When 6M of NH 3 was added, the solution turned dark blue and the test tube was warm. When we added 1mL of 6M NaOH into another test tube a precipitate was formed and was suspended in the solution. The precipitate was light blue in color but the water remained clear, or without color. In a saturated KBr solution, the water turned a brown color. 2. H2O can act as a base or an acid and can change solution reactions. It doesn’t appear in the equilibrium expression constant because it’s understood to be there. Water from the atmosphere is an example.
