Questions & Step-by-Step Solutions
Which of the following is an example of a disproportionation reaction?
Step 1: Understand what a disproportionation reaction is. It is a type of redox reaction where a single substance is both oxidized and reduced.
Step 2: Identify the reactant in the given reaction. Here, the reactant is hydrogen peroxide (H2O2).
Step 3: Look at the products of the reaction. The products are water (H2O) and oxygen gas (O2).
Step 4: Determine what happens to hydrogen peroxide. In this reaction, one part of H2O2 loses electrons (is oxidized) to form O2, while another part gains electrons (is reduced) to form H2O.
Step 5: Conclude that since H2O2 is both oxidized and reduced in this reaction, it is indeed a disproportionation reaction.
