On addition to a small amount of KMnO4 to concentrated H2SO4, a green oily compound is obtained which is highly explosive in nature. Identify the compound from the following.
1. Mn2O7
2. MnO2
3. MnSO4
4. Mn2O3
Hint: In the product, Mn is present in a +7 oxidation state.
In addition of KMnO4, to concentrated H2SO4, a green oily compound Mn2O7 is obtained which is highly explosive in nature.
The reaction is as follows:
KMnO4 + 2H2SO4(conc.) →Mn2O7 + 2KHSO4 + H2O
