Module 2—Talking Energy

Reflect and Connect

There is no doubt that you would use a catalyst if you were to make biodiesel. The procedure you followed in Lesson 1 indicated that either sodium hydroxide or potassium hydroxide could be used. Does it matter which one of these you use?

Save a copy of your completed Assignment in your course folder. You will receive instructions later in this lesson on when to submit your work to your teacher.

Reflect on the Big Picture

In Module 2, Reflect on the Big Picture will prepare you for the Module 2 Assessment in which you will prepare a presentation defending a position on the use of biodiesel by your ecotour company.

So far in this module you have collected information about the following qualities:

• energy content of biodiesel relative to other fuels
• availability of biodiesel relative to other fuels
• cleanliness of biodiesel when combused (emissions testing)
• ease of preparation of biodiesel
• performance of biodiesel under weather conditions in the area in which your ecotour will occur

The final quality you will consider is the catalyst used in the preparation of biodiesel.

RBP 1. Consider the chemical properties of sodium hydroxide or potassium hydroxide, and collect information about the cost and environmental issues related to using these as catalysts to prepare biodiesel. Identify safety issues that you would need to attend to when preparing or using biodiesel.

Save your research in your ecotour planning sub-folder. After you complete this lesson, proceed to the Module 2 Summary and Assessment where you will use the information you have collected to complete the Module 2 Assessment.
