yellow solution = CrO4, and Orange solution = Cr2O7 2CrO4 2- + 2H +? Cr2O7 2- + H20 when the solution is yellow what does that mean in terms of equilibrium, does it mean that the solution will shift towards the products because there is excess of reactants? what does it mean when the solution is orange (is it shifting towards products or reactant)?
