The chemical equation 2KMnO4 + 6H2C2O4 -> K2C2O4 + 2Mn2(SO4)3 + 8H2O + 2CO2

  1. The chemical equation above describes the reaction process between Potassium permanganate (KMnO4) and Oxalic acid (H2C2O4) to form Potassium oxalate (K2C2O4), Manganese (III) sulfate (Mn2(SO4)3), water (H2O) and almond gas (CO2). Each reaction follows the law of conservation of mass, meaning the total number of atoms of each element on the left side equals the total number of atoms on the right side of the equation.

  2. Reaction conditions: This reaction takes place in an acidic environment and works best when the temperature is kept stable at an appropriate level.

  3. Reaction process: KMnO4 and H2C2O4 are mixed together in an acidic environment. The permanganate ions (MnO4-) are reduced down to the state of manganese (II) sulfate (Mn2(SO4)3) while the oxalate ions (C2O4^2-) are oxidized into carbon dioxide gas (CO2). The result is the formation of K2C2O4, Mn2(SO4)3, H2O, and CO2.

  4. Phenomenon occurs: When the reaction occurs, you will see the initial solution which was purple due to KMnO4 turn colorless or slightly pink due to the formation of Mn2(SO4)3. At the same time, CO2 gas will be released, which can be seen as gas bubbles in the solution.
