Industrial chemistry — lime & limestone
Narrated lesson · press play
Limestone is one of the most useful rocks on Earth — and Namibia mines beautiful marble at Karibib. Learn how limestone is turned into lime and slaked lime, the reactions involved, and how these cheap chemicals treat acidic soil, clean up industry and build our world.
What you'll learn in this lesson
By the end you should be able to (NSSCO Chemistry 11.5):
- Describe the manufacture of calcium oxide (lime) from calcium carbonate (limestone) and the reactions involved
- State uses of lime and slaked lime (calcium hydroxide), e.g. treating acidic soil and neutralising acidic industrial waste
- State uses of calcium carbonate (e.g. marble mining at Karibib)
