- Detailed information about the equation 8KMnO4 + 5H2C2O4 -> 8K2C2O4 + 2Mn2(SO4)3 + 10H2O + 2CO2:
- The above chemical equation illustrates the redox reaction between potassium permanganate (KMnO4) and oxalic acid (H2C2O4).
- In this reaction, KMnO4 is a strong oxidizing agent, which oxidizes H2C2O4 into K2C2O4 (potassium oxalate) and CO2 (carbon dioxide gas).
- The manganese atom in KMnO4 is reduced from the oxidation state of +7 to the oxidation state of +3, forming Mn2(SO4)3 (manganese (III) sulfate).
- Reaction conditions:
- This reaction usually occurs in an acidic environment.
- Reaction process:
- Phenomena occurred:
- First, the purple solution of KMnO4 will gradually fade as KMnO4 is reduced.
- Next, the production of CO2 gas can be observed as bubbles rising from the solution.
- Finally, a solution containing K2C2O4 and Mn2(SO4)3 is produced.
