Kris Kelly Chemical Equilibrium Lab CHEM 122L 3/17/08 Background/Theory: In this experiment, various chemical solutions will be added together to reach equilibrium in varying ways. In certain steps, the reaction will shift to the left, the reactant side, and in other cases, to the right, the product side. This shift occurs in order to balance out the chemical reaction because there is either an abundance of reactant or product, creating a need for a shift to either side. A temperature test is done on a CoCl 2 . This is done to determine whether or not the reaction that it undergoes is exothermic or endothermic. Key Data/Results: Part I: Changes in Reactant or Product Concentrations Solution Original Color Addition of conc NH 3 Addition of 1M HCl Addition of conc HCl Addition of water .1 M Cu 2 SO 4 Aqua Blue Dark Blue Aqua Blue n/a n/a .1 M NiCl 2 Light Green Light Purple Light Green n/a n/a 1.0 M CoCl 2 Strawberry Red n/a n/a Brick Red Strawberry Red Part II: Equilibrium Involving Sparingly Soluble Salts
