What happens when a drop of glycerol is added to crushed KMnO4 spread on a paper ? A. There is a crackling sound B. There is a violent explosion. C. There is no reaction. D. The paper ignites

The correct answer is: C. There is no reaction.

Glycerol is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. It is a trihydric alcohol, meaning that it has three hydroxyl groups (-OH). Potassium permanganate (KMnO4) is a dark purple solid that is used as a strong oxidizing agent.

When a drop of glycerol is added to crushed KMnO4 spread on a paper, there is no reaction. The glycerol does not react with the potassium permanganate. This is because the hydroxyl groups in the glycerol are not strong enough to oxidize the potassium
