Product Details

General, Organic and Biological Chemistry Biodiesel is an alternative processed fuel obtained from biological sources, usually vegetable oils, for use in cars and trucks. Alternative fuels such as biodiesel or bioethanol generate a great deal of interest because of concerns about climate change and the depletion of nonrenewable energy sources such as petroleum. In this activity students prepare biodiesel and investigate the amount of energy it releases when burned. Cooking (vegetable) oil is reacted to form a methyl ester by transesterification with methyl alcohol and a strong base. Once produced, the heat of combustion of the resulting biodiesel is determined by calorimetry. Complete for 24 students working in pairs


Materials Included in Kit: 
Canola oil, 32 oz
Methyl alcohol, reagent, 200 mL
Potassium hydroxide, 5 g

Correlation to Next Generation Science Standards (NGSS)

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-3. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS3-1. Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
