The equilibrium system represented by the equation below initially contains equal concentrations of Cr,0,2-(aq) and CrO 2(aq)_. Which of the following statements correctly predicts the result of adding a sample of 6.0 M NaOH(aq) to the system, and provides an explanation? 18/33 Cr,0-2(aq) + 3 H2O(1) 2 CrO42- (aq) + 2 H30*(aq) Orange Yellow (A) The mixture will become more orange because OH will oxidize the Cr in CrO 2-(aq) (B) The mixture will become more yellow because OH will reduce the Cr in Cr2O72- (aq) (C) The mixture will become more yellow because OH will shift the equilibrium toward the products (D) The color of the mixture will not change because OH does not appear in the equilibrium expression
