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...
