a) Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A minus, B minus, and C minus ions, all of which are colorless. When a solution of C is mixed with one containing B minus ions, the color changes from red to yellow. When a solution of C is mixed with one containing A minus ions, the color remains red. Is C more active than A? _____________ Hint: For X2 + 2 Y 1 minus ---> Y2 + 2 X 1 minus If a reaction occurs, X is more active than Y. If a reaction does not occur, Y is more active than X. No Yes b) Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red.
