Another interesting equilibrium system is that between the polyatomic ions chromate, CrO42-, and dichromate, Cr2O72-. In an acidic environment (high H3O+), the chromate will react to form dichromate ion. Barium will react with chromate, but NOT dichromate, to form an insoluble precipitate. 2 CrO42- (aq, yellow) + 2 H3O+ (aq) <---> Cr2O72- (aq, orange) + 2 H2O (l) Describe and explain how the chemical equilibrium will shift and what changes you would observe under the following scenarios: a) Addition of...

2. Explain the effect upon the equilibrium, if any, for each of the substances added (sodium acetate, sodium hydroxide and hydrochloric acid). If you believe that the addition effects the position of the equilibrium, indicate whether the equilibrium shifts toward reactants or products and why.
