The products obtained from a reaction of hydrogen peroxide and acidified potassium permanganate are Mn2, H2O, O2 only.
Explanation:
When hydrogen peroxide (H2O2) reacts with acidified potassium permanganate (KMnO4), a redox reaction occurs. The manganese in permanganate undergoes reduction, while the hydrogen peroxide is oxidized.
The balanced equation for the reaction is as follows:
2 KMnO4 + 3 H2O2 + 2 H2SO4 → K2SO4 + 2 MnSO4 + 8 H2O + 5 O2
Products:
1. Mn2 (Manganese(II) sulfate): The permanganate ion (MnO4-) is reduced to manganese(II) ion (Mn2+) in the reaction. This results in the formation of manganese(II) sulfate (MnSO4).
2. H2O (Water): Water is also produced as a product of the reaction. As the reaction proceeds, water molecules are formed as a result of the combination of hydrogen and oxygen atoms.
3. O2 (Oxygen gas): Oxygen gas is released as a byproduct of the reaction. As hydrogen peroxide is oxidized, it decomposes to form water and oxygen gas. The liberation of oxygen gas is evident in the formation of bubbles or effervescence during the reaction.
Conclusion:
The products obtained from the reaction of hydrogen peroxide and acidified potassium permanganate are Mn2 (manganese(II) sulfate), H2O (water), and O2 (oxygen gas) only. This reaction is a redox reaction where the permanganate ion is reduced to manganese(II) ion, and hydrogen peroxide is oxidized to water and oxygen gas.
