Question
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
