When glycerol (C3H5(OH)3) reacts with potas sium permanganate (KMnO4), a lot of heat can be released. The reaction can be used to start a fire when you go camping. The chemical equation between glycerol and potassium permanganate is given below. A JU student used solution calorimetry to determine the standard enthalpy of reaction During the experiment, 4.582 grams of KMnO4 was added to a 100.0 mL 0.040 M C3H5(OH)3 aqueous solution. The temperature increased from 21.0 C to 34.2 C. Assuming no heat loss during the experiment, that the density of the C3H5(OH), solution is 1.03 g/ml, and that the 0 specific heat of the solution is 4.184 J/g-K.
