1. Higher Chemistry The Kroll Process
NEW LEARNING
Grouping elements by bonding and structure – focus on Titanium
Grouping compounds by bonding and structure.
Periodic trends
REVISION
Elements are the simplest substances and consist of one type of atom.
They are arranged in the Periodic table in increasing atomic number.

2. Lesson 1: The Kroll Process
Today we will learn to
Explain the techniques used to extract titanium, based on the bonding involved.
We will do this by
Watching a video and reading about the process.
We will have succeeded if
We can correctly explain/answer the questions on p40.

3. The Kroll Process

4. The Kroll Process
After discussion with your teacher and others in your class can you explain why:
.An atmosphere of argon used for this reaction?
.Titanium is an expensive metal.
NOTES
Write a brief description of how titanium metal is extracted today and why it is such an expensive metal. Refer to the bonding and properties of each of the substances involved!
