The decomposition of aqueous hydrogen peroxide is catalyzed by
a.
b.
c.
d.
In the reaction between iodic acid and hydrogen peroxide in the presence of starch indicator, the color of the reaction mixture oscillates between deep blue and coloriess. What is the basis of these changes in color? Will this oscillation of color continue indefinitely? Explain. [Hint: Refer to Exercise 97 in Chapter 20 , particularly to equation (c).]
