A group of students is asked to predict which compounds could be added to increase the concentration of dichromate ions, Cr₂O2 (aq), in the chromate/dichromate equilibrium equation represented below. 2 CrO2 (aq) + 2 H(aq) = Cr₂O72-(aq) + H₂O(1) yellow orange Compound 1 K₂CrO4(s) 2 HCl(aq) 3 NaCl(s) 4 H₂O(1) Numerical Response Shift 5 products 6 reactants The colour would become more (Record in the first column) This would cause the equilibrium to shift toward the 12. Using the numbers given above, complete the prediction. To increase the concentration of Cr₂O72-(aq) in the equilibrium system, the compounds that could be added are numbered or (Record in the fourth column) Colour 7 yellow 8 orange (Record in the second column) (Record in the third column) (Record your answer in the numerical-response section on the answer sheet.)
