Textbook Question

Chapter 11, Problem 11.80PAE

The label on a bottle of 3% (by volume) hydrogen peroxide, H₂O₂, purchased at a grocery store, states that the solution should be stored in a cool, dark place. H₂O₂decomposes slowly over time, and the rate of decomposition increases with an increase in temperature and in the presence of light. However, the rate of decomposition increases dramatically if a small amount of powdered MnO- is added to the solution. The decomposition products are H₂O and O₂. MnO₂ is not consumed in the reaction.

Write the equation for the decomposition of H₂O₂.

What role does MnO₂ play?

In the chemistry lab, a student substituted a chunk of MnO₂ for the powdered compound. The reaction rate was not appreciably increased. WTiat is one possible explanation for this observation?

Is MnO₂ part of the stoichiometry of the decomposition of H₂O₂?

You have now performed a liquid-liquid extraction protocol in Experiment 4. In doing so, you manipulated and exploited the acid-base chemistry of one or more of the compounds in your mixture to facilitate their separation into different phases. The key to understanding how liquid- liquid extractions work is by knowing which layer a compound is in, and in what protonation state. The following liquid-liquid extraction is different from the one you performed in Experiment 4, but it uses the same type of logic. Your task is to show how to separate apart Compound A and Compound B. . Complete the following flowchart of a liquid-liquid extraction. Handwritten work is encouraged. • Draw by hand (neatly) only the appropriate organic compound(s) in the boxes. . Specify the reagent(s)/chemicals (name is fine) and concentration as required in Boxes 4 and 5. • Box 7a requires the solvent (name is fine). • Box 7b requires one inorganic compound. • You can neatly complete this assignment by hand and…
