Questions & Answers

Q: What is a disproportionate reaction in chemistry?

A disproportionate reaction occurs when an element is both oxidized and reduced simultaneously, resulting in two different oxidation states.

Q: Can you give an example of a disproportionate reaction?

One example is the reaction of potassium manganate (MnO4-) in an acidic medium, producing MnO4-, MnO2, and water.

Q: How does the oxidation state of the element change in a disproportionate reaction?

In the example of potassium manganate, the oxidation state of manganese changes from +6 to +7 in MnO4- and to +4 in MnO2, showing simultaneous oxidation and reduction.

Q: Are there any other examples of disproportionate reactions?

Yes, another example is the reaction of nitrous acid (HNO2), which produces nitrate (NO3-) and nitric oxide (NO), with nitrogen in different oxidation states of +3 and +2, respectively.

Summary & Key Takeaways

• Disproportionate reactions involve an element in one oxidation state being both oxidized and reduced.

• Examples include the reaction of potassium manganate (MnO4-) in an acidic medium, resulting in MnO4-, MnO2, and water.

• Another example is the reaction of nitrous acid (HNO2) to form nitrate (NO3-) and nitric oxide (NO).
