Questions & Answers

Q: What is the oxidation product of H2S when treated with acidified KMnO4?

When H2S is treated with acidified KMnO4, it is oxidized to form sulfur. The oxidation state of sulfur changes from -2 to 0.

Q: How can sulfur dioxide be oxidized using acidified KMnO4?

Acidified KMnO4 can oxidize sulfur dioxide to form sulfuric acid. The nascent oxygen provided by KMnO4 reacts with sulfur dioxide in the presence of H2, resulting in the formation of sulfuric acid.

Q: What is the oxidation product of sodium sulfide when reacted with acidified KMnO4?

Sodium sulfide (Na2SO3) can be oxidized to sodium sulfate (Na2SO4) using acidified KMnO4. This involves the oxidation of sulfur from an oxidation state of -2 to 0.

Q: How does potassium iodide react with acidified KMnO4?

When potassium iodide (KI) is treated with acidified KMnO4, it is oxidized to form iodine (I2) and potassium sulfate (K2SO4). This is an oxidation reaction where iodine changes its oxidation state from -1 to 0.
