Thermal decomposition of Limestone.
- limestone is mainly calcium
carbonate.
- heating it produces calcium oxide
and carbon dioxide.
- bubbling carbon dioxide
through water makes it
turn cloudy!
- bubbling carbon dioxide
through water makes it
turn cloudy!
- heating it produces calcium oxide
and carbon dioxide.
- some carbonates undergo thermal
decomposition more easily than others
depending on stability.
- sometimes there's a colour change in the substance
- copper
carbonate is
green
- copper oxide is black
- copper oxide is black
- copper
carbonate is
green
- add water to calcium oxide to get calcium
hydroxide.
- calcium hydroxide is used to neutralise acidic soil.
- dissolves in water to create limewater.
- calcium hydroxide is used to neutralise acidic soil.
- this image shows 1) calcium carbonate thermally decomposing into
carbon dioxide and calcium oxide . 2) calcium oxide being added to
water to produce calcium hydroxide (limewater). 3) Calcium hydroxide reacts with
carbon dioxide to form calcium oxide and water.
