  1. What happens when a drop of glycerol is added to crushed KMnO4 spread on a paper ?
    1. There is a crackling sound.
    2. There is a violent explosion.
    3. There is no reaction.
    4. The paper ignites.
Correct Option: B

When solid Potassium Permanganate (KMnO4) is mixed with pure glycerol or other simple alcohols, it will result in a violent combustion reaction. Potassium Permanganate is an extremely powerful oxidizer which spontaneously ignites after coming in contact with glycerol. The glycerol is oxidized so quickly that heat is generated faster than it can be dissipated. 3C3H5(OH)3 + 14KMnO4 14 MnO2 + 7K2CO3 + 2CO2 + 12H2O
