We’re asked to determine why the solution in the middle cylinder has a brownish color based on the given diagram.
The diagram shows the following:
We will determine the substance that caused the brown color in the middle cylinder by getting the overall reaction.
We can see that the decomposition of H2O2 occurs in two steps in the presence of a catalyst (NaBr:
Homogeneous catalysis. Effect of catalyst on the speed of hydrogen peroxide decomposition to water and oxygen gas.
Why does the solution in the middle cylinder have a brownish color?
